In this picture we have from left to right Hippie, Borg & Boar.
Another of Borg, which in my opinion has some of the most badass armour of any Predator from all the movies.
Gort in the foreground, Snake in the background.
Another of Boar, there's also another Predator with a similar helmet called Brother Boar (see below).
Ram on the far left, that's Snake's body next to him, & the body of another which I'm unsure of. There's a final Predator which has the same mask as the original, which doesn't really have a nickname from what I know.
I'm not 100% sure on every one of these, but this is all to the best of my knowledge.
