It depends on the social media platform. For example, on Instagram, you can only see who views your stories if they reply or send a direct message. Other platforms may have different rules and limitations.
In most cases, you can't directly see who watches your stories. Some platforms might give you some general analytics but not specific names.
Sorry, you typically can't know exactly who watches your stories. Social media apps are designed to protect users' privacy, so this information isn't readily available.
