A question mark is a punctuation mark used at the end of a sentence to indicate that the sentence is a question. It signals to the reader that an answer or response is expected. For example, in the sentence "What time is the meeting?" the question mark shows that it is an inquiry.

If the sentence is a question then it does.
No you should only use a question mark.
A period isn't required when you use a question mark. In other words, only one should be used.
A question mark is a punctuation mark, it replaces the use of a full stop at the end of a sentence that is asking a question.
Normally, you would not use both a question mark and an exclamation point in the same sentence. If a sentence is interrogative, it is not an exclamation. An interrogative sentence ends in a question mark, and an exclamation ends in an exclamation point.
