Only five?
We got Cthulhu. Azathoth. Yog-Sothoth. The Goat With The Thousand Young. Nyarlathotep (it's not clear whether he's a messenger or avatar of Azathoth, but he's clearly a separate entity). Hastur (though he's little more than a name). Mother Hydra and Father Dagon (though it's unclear whether either of these is Cthulhu). Magna Mater gets a mention in Rats in the Walls (you might know her better as Our Lady Underground from The Magicians or Joseph Campbell's cheekily named Our Lady of Mammoths or the Stone Age Venus figures). Lilith shows up in Horror at Red Hook, but she could be a Deep One (think the Fomor).
Basically, you can expect a Walker to be Nyarlathotep, the Fomor to be the Deep Ones, and it's possible that they worship Cthulhu.
Edit: And I maintain that the Queens are avatars of Magna Mater, who was Hecate.
