Well, without having read the 'only i can level up novel' thoroughly, it's hard to name all the main characters precisely. However, based on the title, we can assume that there is a central character who is the sole possessor of the leveling - up ability. There may be friends or allies who join the main character on their adventures, and they may also have their own skills and personalities that contribute to the story. There could also be villains or rivals who are envious of the main character's special ability and create obstacles for them during their leveling - up process.

Of course not. 'Leveling up' usually implies progress in skills, knowledge, or personal development. Eating a novel is not only impossible in a practical sense but also has no logical connection to any form of improvement. Our body needs real food like fruits, vegetables, proteins, etc. to function well, and we gain knowledge through reading, studying, and experiencing, not by ingesting the book itself.
I'm not sure exactly who the main characters are without reading the novel, but I assume there's the player who can't level up at the center of the story.
