Yes, "Administrative Office" should be capitalized in a sentence if it is used as a proper noun, such as when referring to a specific office or department within an organization.
The sentence "Have you ever been sent to the principal's office?" is an interrogative sentence because it is asking a question.
No. It is a complete sentence. They (subject) wanted (predicate, with) their own post office(object).
Please have my office visited by you.
It is a fragment as there is no subject. Even if you use it as an answer to a question, it is still a fragment, i.e. "Where is the desk? In the middle of the office." For it to be a complete sentence as an answer to a question, you would need to change the sentence to "It's" or "the desk", "is in the middle of the office."
"must report at the office" is the complete predicate of the sentence. It includes the main verb "report" and the prepositional phrase "at the office."
i will appoint you to the office.

Yesterday I went to the post office to get some stamps.
Yes that is a correct sentence, as long as you have identified who "he" is in a previous statement.
