Answer 1

Calories are a way to measure the amount of chemical energy in a substance. It answers the question of “how much energy can be released by breaking this substance down?”

100 calories of sugar are equivalent to 100 cals of protein, yes.

There is no flat out answer for your last question. Everyone has different daily demands for calories.
