In 'my professor is my alpha mate novel', the main character is surely the one who has the professor as an alpha mate. This character might be a young, impressionable student. The professor, being the alpha mate, is another key character. There could be other characters like classmates who notice the strange relationship developing, or family members who have different reactions to the situation. These additional characters can add depth and complexity to the story.

Given the title 'my mate is a fool novel', we can guess that there is a narrator who has a mate. The mate is obviously one of the main characters.
