First of all, the format of this paper depends on the school, and some schools have their own regulations. It's best to see if the school has relevant requirements first.
Your first question: I won't talk about the specific definitions of footnotes and endnotes. We need to annotate and quote references in the paper. Footnotes can be used as comments, that is, you think that a certain paragraph of your speech has no comments, which affects others' understanding and is located at the footer; Endnotes can be used to edit references at the end of the whole document.
The second one: their format is related to the requirements of the school. Footnotes generally use circled numbers, and endnotes generally use numbers in brackets. Such as [1] weeks.

Third, the English letters in brackets indicate the sources of information, such as M for books, J for periodicals, C for meetings, N for newspapers and so on. I am a liberal arts student. If you are a science student, you should have a patent P, a database db and so on.
According to the requirements of master's thesis in our school, at the end of references and after names, English periods are generally used. If there are multiple authors, Chinese commas will do. Colons are usually used before the address of a publishing house, such as Beijing: People's Publishing House.
Finally, more importantly, the format of the text and the title is different. If you have any questions, I can send them to you for reference.
