That yellow missile and the red missiles look like they could be from the Centurions line -- but I'm not 100% certain.

In the second picture you have a few silver figures and one gold figure: they are from the "ZOIDS" toylines. Some of the grey weapons are ZOIDS too.
Thanks for the help so far, I greatly appreciate it! I'll basically put these in my "odds n ends" drawer and if I run across the figure they go to somewhere, hopefully I can reunite them.
The red screwdriver looking thing goes to Zod from "Go-bots"
