I don't know the answers. I agree with most of what Leisher said.

9 - Could be Baby Ruth.
10 - Nestle (it literally says the name on it)
11 - Heath
12 - Butterfinger?
13 - Mr Goodbar?
14 - Sour Patch Kids
17 - Peanut M&Ms?
42 - Jelly beans?

2/4/8 all look nuggety to me: 3 musketeers, snickers, or Milky Way.

I think 1 or 11 are Heath.
