So I assume you mean the actors who portray them right?
For me I think they are all very good looking in their own way. (Even Taylor/Jacob even though I can't stand the character he plays.) I think they are all HOT guys. We seriously have THE HOTTEST cas I have ever seen for one movie! Even the girls Bella, Esme, Alice, Rosalie, Jessica, Angela. They are all beautiful girls too.
Because Edward is Edward, romantic, gentleman, protective and so on. Doesn't need to explain. *wink* ;)
Because he is so hot, funny and sweet teddy bear. :)
Duh, he is handsome doctor. (And compassionate) Who wouldn't love him? *wink* ;)
Because he has those enchanting eyes. And I love his accent. :)
