Small white gun belongs to G1 blades....
And the grey guns and red accessorys belong to Getsuei and Shouki.
The black guns look like they belong to one of the Stunticons (not Motormaster).
That black twin cannon is First Aid's - not of a stunticons

Click on the individual trainbots for their accessories. The red pieces belong to Shouki and Getsuei. The dark grey guns also belong to Shouki and Getsuei.
I am unsure about the lighter grey gun.
