Atris was in love with him long ago, probably still but she refuses to admit it and you can never get anything with her. Even if the game would be finished you wouldn't, she would turn to the Dark Side because of you though and possibly replace the roll of Kreia as the final boss, of course that was never put into the final version of the game.
Handmaiden is in love with you, or at least so it seems. Again nothing would have really happened, at least I don't think so.. I don't really remember.
Visas cares for you but not in that way, its more because of what she see's then what she feels.
Mira would if I remember correctly be the girl you would get to date, she would fall in love with you of course the dialogue was never finished. But she would start tto play a far more vital role in the game if you were lightside then she does now.
