Part 1:
#13, is a weapon for Beast Wars Optimus Primal (gorilla version).
#14 is a disc for Beast Wars Depth Charge (the big manta ray)

Part 2:
Many of the gold & orange weapons in Part 2 are from DragonHeart toys.
#3 is a leg (one of 8) for Beast Wars Transmetal Tarantulas.

Part 3:
1/2, 11/12, 17, 24 - these are early Kenner Star Wars Power of the Force 2 weapons, from the late 1990s. (Part 5, #31, is also from that line, from Luke Skywalker v1)
8/13, mostly sure is a weapon off a GIJoe vehicle. Not thinking of which right now. I know I have that piece myself.
19 is the fuel pump accessory for an original-version Optimus Prime (1984 or G2, or any reissue)
20 is a GIJoe rifle, came with Cutter (1992) (which came with a medium size boat called the Shark 9000 - a depth charge that came with that toy, is Part 6, #8)
All of these came with the 1994 GIJoe Action Sailor: 18, 23, 25, 27, 28
22 is the mask for Cobra Air Devil, 1992 (90% sure).

Part 4:
I don't recognize any of these things.

Part 5:
#8 is a GIJoe gun, came with SciFi in 1991 & 1993, and with star Brigade Destro (1993).
18 is from "Crime Solver Robin, of the New Batman Adventures. part of a sled accessory, it's the handlebars.
17, 22: Dragonheart again, I think

Part 6
03 is a missle from a Batman Animated toy. any item with a similar stick (rounded, with a notch about 1"-1.5" in, and with a flat bisect like that piece) is also prob from a Batman animated toy or other 90's Kenner.
12 (sword) is from Transformers G1/G2 Slag
17/18 is a missle from the GIJoe Extreme Sandstriker vehicle
