Question

if you are smart this is easy

Answer 1

Two different subjective pronouns: 
~ they
~ their

Two objective pronouns functioning as a direct object:
~ it
~ their

One objective pronoun functioning as an object of the preposition:
~ them

Two possesive pronouns:
~ their
~ ?

One intensive pronoun: 
~ itself

I couldn't come up with another possesive pronoun in your reading other than their. I hope somebody else can help you find one!
