Light reflects when it hits aluminum foil. In fact, anything that you can see reflects light. Without the reflecting light reaching your eyes, you would not see it at all.
Yes all metal foils reflect heat (and other electromagnetic radiation: light, radio waves, etc.).
Mainly aluminum because of its light weight. Other metals (steel and copper predominantly) as needed.

Yes. For a while a bunch of houses were wired with aluminum. Problem is that when you mix aluminum and copper wires you create a fire hazard.

A light brown mixed that is made by mixing brown with a light yellow
The aluminum foil reflected the rays of the light, so without the foil the ice cube couldn't reflect any of the light's rays and that made it melt faster
Most likely you have seen a fake. Someone probably electroplated an ordinary 1976 d penny with silver or aluminum. Check its weight. Aluminum is light, less than 1/3rd the density of copper. Compare its weight with a copper penny. If the "aluminum" penny is just as heavy, then it is a electroplated penny. If it is light, then it is a complete fake.
Bronze cannons can be a brownish-green color in saltwater. On land it ranges from a white, talc yellow or light green oxidation that brushes off easily.
Any conductor like copper or silver or aluminum
