Well, the idea behind a pot holder is that it acts to keep your hands or the surface the hot dish is placed on from being burned. If the material were a good conductor of heat, you'd burn yourself. The materials used to make pot holders are expected to be poor heat conductors because they are expected to keep you from burning yourself.
a poor thermal conductor.
A key would be a conductor. ------------------------------------------------------ That would depend on what the key was made of. Keys made out of metals would be conductors, while contactless plastic car keys would be insulators.
It is an isulator as it allows thethe current to pass through it ...
it would be a conductor, as most metal conducts electricity.
No, a basketball would not be a good conductor. It's, however, made from rubber which is an excellent insulator.In the image above the conductor would be the copper metal inside the wire. It conducts and passes the energy particles along it - because the metal allows for the energy to freely move through it.The insulator, or our basketball, would be the pink, orange/yellow, green, and blue coating covering the conductor. It's responsible for shielding or insulating the wire from arcs, interference, and electrical overload from coming into contact with other conducive materials (humans are conducive).

a poor thermal conductor.
Materials with low thermal conductivity such as rubber, glass, and wood are good insulators. These materials are poor conductors of heat, so they do not easily allow heat to pass through them.

No, cheese is not a conductor of electricity. Conductors are materials that allow electrical current to pass through them easily, while cheese is an insulator and does not conduct electricity.
a poor thermal conductor
Yes; but the vast majority of uses would require licenses from the copyright holders.
