There are female version of Michael in the shinyaku last Bible mobile games
another is a female form of Beelzebub from majin tensei 2
Lucifer has 2 female form one is gender bend version of Louis cypher from smt image the other is Louisa Ferre from strange journey
Satan humorously has 2 from iv/apocalypse Because he impersonates Lucifer as hikaru and Gabriel as Gabby
Also Gabriel who form has been female since smt ii
Also Mara has a female form in last Bible ii
Also Susano'o has a female form in megami tensei ii (although this is a disguise)
Melissa is a demon based on a porn virus from demikids
Ishtar is one
Another is Astarte from giten
Amaterasu is another
Oh yeah also Eve from smt:Nine
Lilith and the Qadistu (which are probably already planned given naamah)
Izanami is one more
