The ak rifle to the right is called the “ak-12”. I’m pretty sure that some of the armed forces in Russia us that along with the ak-47. But I’m not so sure though.

Great. Now we can add those to the tags.

Fourth row left is actually the FN FAL.

I think I can name 5, or name the family they are from.
 
so first is row one left side looks to be a variant of AK mainly going of the large fire selector switch as its the same as Ak and rpd use.
 
second is second row right side looks like the modern M14 I know they look way different then the wood stock version.
 
third is row 3 right side witch looks to be another Ak family gun by the bolt slide and barrel.
 
fourth is row 4 left witch is Gaile or similar gun.
 
Last is the one I am 100% sure of row 4 right side is a HK G11 or more often called krout space magic or if your a Girls Frontline player sleepo beepo of the 404 team.  

I wish I could identify these weapons like they do so easily at IMFDB.
