There are five types of pronouns in English: personal, possessive, reflexive, relative, and demonstrative.
Personal pronouns are used to refer to specific people or things, and they can be either singular or plural. Possessive pronouns are used to show ownership, and they can also be either singular or plural. Reflexive pronouns are used when the subject and the object are the same. Relative pronouns are used to introduce relative clauses, and demonstrative pronouns are used to point out specific people or things.
