Since I don't know the exact story, it's difficult to say. But most likely, the disappearing man is one of the main characters. There might also be characters who are related to him, like his family members or friends who are affected by his disappearance.
I'm not sure specifically as there could be many stories with this title. But generally, it might be about a man who mysteriously vanishes. It could involve elements like a search for the man, the reasons behind his disappearance, and the impact of his vanishing on the people around him.
Mr. Hawkins is another important character. He is Dave's employer. His relationship with Dave shows the power dynamics between an employer and a young, inexperienced worker. Dave wants to prove himself to Mr. Hawkins as part of his journey to manhood.
It's hard to determine the main characters precisely without having read the story. However, the burning man is bound to be a central figure.

Maybe there's a character who has a past connection with the burning man and that connection drives the plot forward.

Obviously, the main characters are the rent man, who comes to claim what is due, and the tenant.

The main character is the umbrella man. There might also be the person to whom he tries to sell his umbrella.
The two main characters are the man and the donkey. The man might be the one who has the agency in the story, making decisions about where they go and what they do.

It might have its own personality, like being lazy or hard - working, which would influence the story's development.
As I haven't read the story, I can't be certain. But the man with the umbrella is surely one of the main characters. There might be other characters like people he meets on his way, such as a passer - by who notices his umbrella or someone he has an interaction with because of the umbrella.
I don't know for sure without reading it, but surely the man upstairs is one of the main characters. There might also be neighbors or people who interact with him, like the landlord or a curious neighbor from downstairs.
