I have already asked this question from some teachers and student, some say these are present simples but in present simple we use "do/does" and etc. I want to know which type of sentences these are.

Questions employ do/does only if there is no other auxiliary verb present to invert with the subject. This is called "do support":
I finished yesterday. → Did you finish yesterday? —There is no auxiliary here, so finish requires "do support" to provide an auxiliary that can invert with the subject in a question.
I have finished. → Have you finished? — have here is an auxiliary, so it can invert with the subject in a question.
I have a new car. → Do you have a new car? — have here is not an auxiliary but a lexical verb, so it requires "do support" in a question.
Sentences with a form of BE, however, work a little differently. BE is always treated as an auxiliary, even when it is the only verb:
I am finishing the project today. → Are you finishing the project today? AND
I am finished. → Are you finished?
Note, by the way, that for some speakers HAVE can also be treated as an auxiliary when it is the only verb.
I have a new car. → Have you a new car?
This was once very common, but it is slowly disappearing; it has an old-fashioned ring now.
