Greetings!
Because there are a number of accepted forms, the answers to your questions depend, in large part, on what type of paper it is and which citation system you are using. For example, if you were writing a psychology paper, you would probably be using APA citation, in which case your paper should have a title page and a running head at the top of each page. If you are using MLA, on the other hand, your name should appear at the top right of each page, just in front of the page number.
If you have not been told to use a specific citation format, and your instructor has not specified a preference, then you might want to just pick one, MLA, for example, and just stick with it unless told otherwise. It's easy to find "how-to" information on citation styles online; just search "MLA citation."
I hope this helps!
