Which movie will be the most successful? Thor, Green Lantern, or Captain America?

Thor or Captain America will be the best movie (my guess is Thor but it's too early to tell). But Green Lantern will easily win the box-office battle, because it stars the newly-single Ryan Reynolds, who is People Magazine's iest man of 2010. That brings in female moviegoers, which as we saw with Titanic, are a hugely important demographic for a movie's commercial success.
