Sebastian -> Gay, as far as we know from the show. But I could see him being pansexual.

Dean -> Straight (or maybe the least bit bicurious)

Balthazar - > Omnisexual

Jack Harkness -> omnisexual

Lucifer -> asexual, mostly.

Jesse -> straight

Raphael and Lucifer can bond over judging angels who screw their way around the planet y/n/m?

Yes.
