Picture 1:
#1-4: none of these missiles are GI Joe items.
I think #1 is by Kenner because they used a lot of ball-lock missile launchers. No clue on the rest.

5. gun from one of Lanard's The Corps! S.T.A.R. Force astronauts. carried by at least 2 different figures based on quickie google.
(do an image search of "lanard space action figures" and look at the first picture that comes up. aside, I had no idea there was a sub-line of astronauts on HORSES.)

6. G.I. Joe gun - Low Light, either 1991 or the 2001 repaint. Also came with 2002 Neo-Viper (GI Joe vs Cobra line).

7. Masters of the Universe Trap Jaw laser arm accessory

Picture 2:
these are not G.I. Joe accessories. I don't know what they're from.
Ridiculous-looking enough to be from TMNT or Batman TAS, but neither often had black weapons and the flashing on part #2 would indicate some cheapo brand.
