amiga translates as "friend", it is also worth noting that amiga is the femanine version of friend, so more exactly an amiga is a female friend, just as an amigo would be a male friend
You would say "Ella no es tu amiga." (or su amiga for the formal you, usted) If you mean 'She is not my friend' - "Ella no es mi amiga".
That would translate over to: "She is a friend"
I need my friend.
Friend (female)
It means "my friend (female)".

"Que desea amiga?" is a phrase in Spanish. It means "What do you want, friend?" or "For what do you wish, friend?". The fact that "amiga" was used means that the speaker was talking to a female (versus "amigo").
