Let me guess:
91/30
M44
SKS
AK-type derivative; possibly a WASR
SVT
SMLE x3
A different Enfield rifle
???
AR15-type rifle; can't name the make
M14/M21/M1A
M1 Carbine
M1 Garand
???
Mosin with scope
There's a P38 and PP/K in there somewhere...
???
P38, as previously mentioned.
AK-type rifle, with thumb-hole stock, a scope that's rail-mounted (can't tell how from this pic) and clips holding 2 30(?)-round magazines together.
Suppressed M10-looking submachine pistol. Nice trigger discipline there btw

Nice pose and facial expression there, almost as if: "Specimens? My trusty rooty-tooty-point-and-shooty will take care of them"
Some bolt-action rifle, probably in 7.62x51mm NATO, or the civilian equivalent, .308 Winchester.
