We don't really know without reading the story. However, in a group - based short story, there are often characters with distinct personalities. There might be a rational thinker among the twelve men who tries to analyze the situation when the thirteenth man arrives. There could also be an emotional character who reacts strongly to the new addition. And of course, the thirteenth man, who might have his own backstory, motives, and personality traits that make him either a likable or controversial figure in the story.
Typically in a story like this, there could be a protagonist among the thirteen men. It could be the thirteenth man himself, who is facing some sort of struggle, whether it's against the group of twelve or some external force. There might also be an antagonist, which could be one of the twelve if they oppose the thirteenth man's presence. And then there could be other supporting characters among the twelve, like a friendlier one who tries to bridge the gap between the thirteenth man and the rest of the group.
I'm not sure exactly as I haven't read this specific short story in detail. But generally, it might be about a group of twelve men and then something special or different about the thirteenth man that drives the story, like a mystery or a conflict related to his presence.

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. The donkey, on the other hand, is an important part as it provides the means of transportation or labor. 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.
