I hope this sort of post is allowed here. I’ve been working on this but I’m not very knowledgeable on guns so I’m not super sure of my guesses. Specifically I’m trying to work out what sort of ammunition each uses, but the type/model of gun would help too.

I’m wondering if 2 and 5 are variants of the Galil. There’s also might be a FAL in the mix for one of the other unknowns. I’m on mobile so it was really hard to get a great look.
