An electrical insulator is an object that's internal charges do not move freely. This makes it nearly impossible to conduct electricity. Some examples of insulators are, Styrofoam, most plastics paper, glass, and rubber.
The best insulator of heat is probably polystyrene foam or fiber glass.

Styrofoam is the best material to use as an insulator. Styrofoam is the best insulator, since the temperature of the water in the styrofoam glass decreased the least. If you mean what "state" of matter is the best insulator then you're probably looking for gas as the answer. The state of matter that is best as a thermal insulator is gas.
Dead air space, or motionless air.

A material that doesn't conduct heat well is called an insulator.

Fiberglass.
any material that does not conduct electricity is an insulator.
Exfiltration
Most probably an insulator. But shoe lace isn't a material, it's an item. And it's the material that decides if an item is an insulator or not.
Yes but it depends on the type of material.
