Andrealphus (also Androalphus) appears as the 54th demon in Johann Weyer's tome on demonology Pseudomonarchia Daemonum and is described as a great Marquis with the appearance of a peacock who raises great noises and teaches cunning in astronomy, and when in human form also teaches geometry in a perfect manner. He is also described as ruling over thirty legions and as having the ability to turn any man into a bird. Andrealphus also appears as the 65th demon in the Goetia where he is described with similar traits, but also including the ability to make men subtle in all things pertaining to Mensuration, among other things.

Asmodeus (/ˌæzməˈdiːəs/; Ancient Greek: Ἀσμοδαῖος, Asmodaios) or Ashmedai (/ˈæʃmɪˌdaɪ/; Hebrew: אַשְמְדּאָי, ʾAšmədʾāy; see below for other variations), is a prince of demons,[1] or in Judeo-Islamic lore one king of the earthly spirits called the Ars Goetia, mostly known from the deuterocanonical Book of Tobit, in which he is the primary antagonist. In Peter Binsfeld's classification of demons, Asmodeus represents lust. The demon is also mentioned in some Talmudic legends; for instance, in the story of the construction of the Temple of Solomon.

Astaroth (also Ashtaroth, Astarot and Asteroth), in demonology, is the Great Duke of Hell in the first hierarchy with Beelzebub and Lucifer; he is part of the evil trinity. He is a male figure most likely named after the Near Eastern goddess Astarte.

The name "Astaroth" as a male demon is first known from The Book of Abramelin, purportedly written in Hebrew c. 1458, and recurred in most occult grimoires of the following centuries. Astaroth also features as an archdemon associated with the qliphoth (adverse forces) according to later Kabbalistic texts, as he rules over the qlipha of Jupiter, known as Gha'agsheblah.

Dutch demonologist Johann Weyer also described Astaroth in his Pseudomonarchia Daemonum (1577) thus: "Astaroth is a great and a strong duke, coming forth in the shape of a foul angel, sitting upon an infernal dragon, and carrying on his right hand a viper", who also claimed to rule 40 legions. Also, he had to be approached by the conjurer with a magical ring on account of his stinking breath. He is similarly referred to in the 17th-century work The Lesser Key of Solomon. He also makes an appearance in the notorious "Grimorium Verum" (True Grimoire), as the infernal principality which rules the Americas.

According to some demonologists of the 16th century, August is the month during which this demon's attacks against man are stronger. According to Sebastien Michaelis, he is a demon of the First Hierarchy, who seduces by means of laziness, self-doubt, and rationalized philosophies. His adversary is St. Bartholomew, who can protect against him for he has resisted Astaroth's temptations. To others, he teaches mathematical sciences and handicrafts, can make men invisible and lead them to hidden treasures, and answers every question formulated to him. He was also said to give to mortal beings the power over serpents.

Was mentioned as a co-signatory of a Diabolical pact with Urban Grandier.

According to Francis Barrett (c. 1801), Astaroth is the prince of accusers and inquisitors. In art, in the Dictionnaire Infernal (1818), Astaroth is depicted as a nude man with feathered wings, wearing a crown, holding a serpent in one hand, and riding a beast with dragon-like wings and a serpent-like tail.

Balam (also Balaam, Balan) is a great and powerful king of Hell who commands over forty legions of demons. He gives perfect answers on things past, present, and to come, and can also make men invisible and witty. Balam is depicted as being three-headed. One head is the head of a bull, the second of a man, and the third of a ram. He has flaming eyes and the tail of a serpent. He carries a hawk on his fist and rides a strong bear. At other times, he is represented as a naked man riding a bear. His name seems to have been taken from Balaam, the biblical magician.

Baʿal Berith ("Lord of the Covenant") and El Berith ("God of the Covenant") are two gods, worshiped in Shechem, in ancient Canaan, according to the Bible. The term for "covenant" (Hebrew bərīt) appears also in Ugaritic texts (second millennium BCE) as brt, in connection with Baʿal, and perhaps as Beruth in Sanchuniathon's work.

Judges is the only Biblical book that mentions Baʿal Berith and El Berith. It is not clear whether they are actually one god, nor whether they are separate forms of Baʿal and El. Scholars suppose that he or they may have been worshipped for connections to fertility and vegetation, based on another passage in Judges. Also unclear is what covenant or covenants are referred to by the name Berith. Elsewhere, some of the Shechemites are called "men of Hamor"; this is compared to "sons of Hamor", which in the ancient Middle East referred to people who had entered into a covenant sealed by the sacrifice of a hamor, an ass. "Children of Hamor" or "sons of Hamor" itself appears in Genesis and Joshua, in both of which, as in Judges, Hamor is called the father of Shechem. Genesis also features a man named Hamor who ruled in the area of Shechem and had a son named Shechem.

Rabbinic tradition equates Baʿal Berith with Beelzebub, the god of Philistine Ekron.

In demonology, Ipos is an Earl and powerful Prince of Hell (a Duke to some authors) who has thirty-six legions of demons under his command. He knows and can reveal all things, past, present and future (only the future to some authors, and past and future to others). He can make men witty and valiant.

He is commonly depicted with the body of an angel with the head of a lion, the tail of a hare, and the feet of a goose, less frequently in the same shape but with the body of a lion, and rarely as a vulture.

Other spellings: Aiperos, Ayperos, Ayporos, Ipes.

The demon Naberius was first mentioned by Johann Weyer in 1583. He is supposedly the most valiant Marquess of Hell, and has nineteen legions of demons under his command. He makes men cunning in all arts (and sciences, according to most authors), but especially in rhetoric, speaking with a hoarse voice. He also restores lost dignities and honors, although to Johann Weyer, he procures the loss of them.

Naberius appears as a three-headed dog or a raven. He has a raucous voice but presents himself as eloquent and amiable. He teaches the art of gracious living. He has also been depicted as a crow or a black crane.

Concerning his name, it is unclear if there is an association with the Greek Cerberus. It is said that in 1583, Johann Weyer considers both of them to be the same demon. He claimed:

Naberius [Naberus], alias Cerberus, is a valiant marquesse, shewing himselfe in the forme of a crowe, when he speaketh with a hoarse voice: he maketh a man amiable and cunning in all arts, and speciallie in rhetorike, he procureth the losse of prelacies and dignities: nineteene legions heare (and obeie) him.

Other spellings include Cerberus, Cerbere, and Naberus.

He is depicted as a horse that changes into a man under the conjurer's request.

The name could come from the Latin 'orobias', a type of incense.

Valac is a demon described in the goetic grimoires The Lesser Key of Solomon (in some versions as Ualac or Valak and in Thomas Rudd's variant as Valu), Johann Weyer's Pseudomonarchia Daemonum (as Volac), the Liber Officiorum Spirituum (as Coolor or Doolas), and in the Munich Manual of Demonic Magic (as Volach) as an angelically winged boy riding a two-headed dragon, attributed with the power of finding treasures.

The Lesser Key, the Munich Burnich, Rudd, and Weyer further agree in ranking Valac as a president and attributing him with the power to locate, summon, and control serpents. The Officium Spirituum similarly attributes Doolas with the power to give the summoner command of serpents as well as "household spirits," but it ranks Cooler and Doolas as princes instead of presidents. Valac is listed 62nd in the Lesser Key (even by Rudd) and the 49th by Weyer, with either version claiming he leads 30 legions of demons (though some manuscripts say 38). The Munich Burnich describes Volach as controlling 27 legions of spirits. The Officium Spirituum (depending on the manuscript) ranks Coolor as either 21st (with no note of how many spirits he commands) or (in the copy found in the Folger Shakespeare Library) 22nd and commanding 13 legions of spirits. All extant and complete versions of the Officium Spirituum list Doolas as 25th demon, commanding 20 legions of spirits.
