34 - sword for Transformers Dinobot Sludge (1985)
43 is from Mighty Crusaders (Remco, 1980s, based on Archie Comics superhero characters) -- a rifle that came with The Comet, The Web, and The Buzzard
22 I'm pretty sure is a Transformers gun but I can't place it.
7 looks to be an M-60 from the A-Team 3 3/4 inch line (because of the handle, which the 80s GIJoe version of the same gun didn't have)
