Yes and no.
Angels , similar to Lucifer, are/were the "host of heaven".
Lucifer is a specific type of heavenly host, a "Cherub".
These are seen as the 2 you find when you look at a artist's rendition of the "Ark of the Covenant".

Every angel that appears in the NT is seen as a Male, in human forum, and none have wings.
Angels have free will, and some chose to follow Lucifer, and became "demons".
According to Genesis, Angels can have sexual relations with humans.
Angels are not bound by time and space.
1.) How is a human different from the heavenly host, including Angels?
Genesis says that Man is "created in the image of God" .. made alive by the Spirit of God., and Angels are "ministering Spirits".
Jesus says of mankind......>"ye are gods", and He does not say this about Angels.
Angels can "fall" and are never born again.
"Man"..... are "adamic nature" "fallen" and can be born again.
