What different types of copper do I have?

I am recently getting back into scrapping now that it is the summer and I am wondering what types of copper do I have. I attached a pic to what I have.
Also wondering if there is such a thing that is copper coaxial cable. (#4) in the picture below.

#1: This copper wire is hard and bendable.
#2: I dont know if this is copper or not. Its darker than the other copper.
#3: This came out of a tv.
#4: THIS is the question I have - is this copper or some sort of copper colored aluminum. It was webbed together like a coaxial cable.
#5: This wire is more red and is also covered in some sort of glue - Do I need to get rid of the glue in order to scrap it?
#6: Do I need to strip the wire of these to scrap them??

I believe this is all copper wiring - my question is do I need to strip all of this in order to scrap it or will a regular yard take it as is?
