Obviously, the little girl and the bear were both main characters. The story likely revolved around their interactions, whether it was a friendly encounter or some sort of conflict between them.
Since I don't have any information about the 'Mysterious Mr Richard Novel' other than its title, it's difficult to determine the main character precisely. It might be Mr Richard, but novels often have complex casts of characters. There could be a character who is narrating the story about Mr Richard, and that narrator could also be considered a main character in a sense. There could also be an antagonist in the story who is in opposition to Mr Richard, and that character could play a major role as well.
I don't know who specifically wrote this story. There are so many authors out there who could have created a scary teddy bear story.
The main character is the libertarian. Their beliefs and actions are central to the story. We can assume that the author wants to show how this person's libertarian views interact with the situation of coming across a bear. It could be that the story uses this extreme situation to explore the boundaries and implications of libertarian thinking.
If the 'jezebel scary story' follows a traditional horror plot, Jezebel is probably the main character. She could be a complex character, perhaps a once - good person who was corrupted by some dark force. Or she could be a pure - evil entity from the start, preying on the innocent in the story. Maybe she has special powers that she uses to terrify others, like the ability to control shadows or read people's minds to find their deepest fears.
