I don't think there are any questions on this worksheet. It is just explaining how to say each pronoun in Spanish.
I --> Yo
You (informal-a peer) --> Tu
He --> El
She --> Ella
You (formal-an adult) --> Usted
We --> Nosotros(as-for females)
You all (informal) --> Vosotros(as)
They --> Ellos(as)
You all (formal) --> Ustedes
Hope this helps!
