Not correct. Also, the idiomatic imperfect with "used to" is rather informal for an essay. Use Was that not a school ( you could use wasn't that a school, but generally we avoid contractions in serious essays). If you feel you must use "used to," put the question at the end: That used to be a school, did it not?
No, the question is not grammatically correct. It should be "Does she have a pen?" using the correct form of the verb "have" for the subject "she."
