Which story characters should be together?

I have one character named Gossamer Fiona Paine. There are 4 male characters named Thane, Leo, August, and Gabriel. Thane is a military general and is not bothered by physical pain and doesn't let things get in his way. Leo is sarcastic, caring, and he is a spy. August is the Prince of this one place or whatever and is protective. Gabriel is an in and is kind of dark, and really smart. They are all in love with Gossamer. Who would be the best for her?
