The Witcher and Elric I recognize, but the other two are eluding me. Some prats from GoT maybe?
Does Geralt have a second (empty) scabbard on his back, or is he just carrying a spare sword around for the fun of it?
Poor Elric seems very hunched over for a tall, slender Melnibonean, although it might just be the angle of the photo. Perhaps he's thrown his back out trying to swing that pigsticker...er, Stormbringer one handed like that? "By Arioch, my sciatica! Moonglum, bring the linament!"
I do like the boneboys and their boss doing the Hamlet impression. Don't guess the musician's getting much sound out of that thing with no lungs and all, though.
