Can you identify these parts and assemblies?

Question

I just spent a lovely afternoon going through a box of childhood (40+ years ago) identifying bricks, but ended with a half dozen I couldn't. Here is a picture:

I know some are newer, but some are original (3 & 6)

If you could help me find the actual part numbers I would appreciate it.
