What pronouns can you use to replace the first and second person pronouns?

Answer 1

he, she, you, we, they and I

Answer 2

First person pronoun: I

Second person pronoun: You

To replace /I/, one must say: (but it will be slang or bad grammar)" Hey yous! Me! Listen up yous! ME first. My talking!"

Other than incorrect usage, I know oof no other way to replace a first person pronoun.

Second person pronouns can be old fashioned:

"Thou shalt be quiet in the church."
