How does one determine the amount of energy is a rubber band that has been twisted numerous times. As in a rubber band propeller engine

Instead of a propeller attach it to a light drum pulley. Attach one end of a rope to the pulley so that it it would wind as the pulley turns and the other end attach to a known mass m
Energy stored will be equal to potential energy or work done against gravity
E=mgh.
Just measure the mass m and height h and you got it.

you would have to know the chemical properties of the rubber band otherwise it is the amount of energy you used to twist it.

elastic ability! there are a number of styles of ability: chemical ability, warmth, electromagnetic radiation, ability ability (gravitational, electric, elastic, etc.), nuclear ability, relax ability. those could be categorized in 2 important instructions: ability ability and kinetic ability.
