Should I subtract every window and door?

For accuracy, yes — sum up all door and window areas and enter the total. Some contractors skip small deductions since trim work around openings adds labor anyway.

How much stucco material does this area require?

Material needs depend on the number of coats and thickness — check your specific stucco product's coverage rate per bag, then divide your total area by that coverage rate.
