I run into this once and awhile during prayer sessions, that is, demons
posing as female.  For the record, there is absolutely zero Biblical
references to female angels of which I am aware.  I suppose there could be
female angels but the bible, Jesus Himself in fact, said that angels in
Heaven are not given in marriage.  This does not, of course, imply all
angels are male but I for one cannot think of a single female angel in the
bible.  I used to pray with a man in Korea.  Nearly all spirits in Korea
history are female and they ain't angels based upon their desire for
worship, desire for spiritual sexual intercourse, and the like.  Before one
begins believing that God sends female angels with messages to us, I would
frantically search the scriptures for a precedence before I believed in
communicating with female angels by any name.  Just one man's opinion, of
course.
