Hanharr - yes.
G0T0 - yes.
Kreia - no. Kreia is a great character. She may be an annoying, manipulative old hag, but she's still one of them most wonderfully developed characters I've seen in a computer game in a long time.

Yeah... so great that they almost forgot about the Exile and his role.
Kinda sucks not beeing the main character in an RPG.

You could choose to leave Kreia on the ship the entire game. She doesn't come close to being the main character, however she happens to be the deepest NPC in the series.

No, you can't.
