Explanation
A pronoun is a word that takes the place of a noun in a sentence.
There are different types of pronouns.
Personal pronouns  are subject pronounswhen they take the place of a noun as the subject of a sentence
(I, you, he, she, it, we, and they), and object pronounswhen they take the place of a noun as the object of a sentence (me, you, him, her, it, us, them). 
 I (subject pronoun) met him  (object pronoun) in the street.
Possessive pronouns  take the place of possessive nouns and show who or what owns or has something. 
Possessive pronouns my, your, his, her, its, our, their come before a noun. This is my book.
Possessive pronouns mine, yours, his, hers, its, ours, theirs appear without a noun. This book is mine.
Indefinite pronouns  (some, any, and no) show an indefinite quantity of something, an indefinite number of
people or things. We use some in affirmative sentences (+), any in interrogative (?) and
negative sentences (-), and no in negative sentences. There are some flowers in my garden.
Are there any flowers in my garden? There are not any/no flowers in my garden. 
We also use some in questions that are requests or offers. Would you like to buy some cakes?
Demonstrative pronouns  (this - these, that - those) show distance - this and that  take the place of
singular nouns; these and those take the place of plural nouns.
This is very interesting. You can see that from here.
Interrogative pronouns(who, whom, whose, what, which) are used to ask questions.
What are you doing?
