Pronouns act as stand-ins for nouns.
Subject pronouns are the subject of a sentence.
Object pronouns are the object of a verb or preposition.
The subject personal pronouns are: I, you, he, she, it, we, they. They are used when they are the subject of the sentence, when they perform the verb - not when the verb is performed on them: I am the subject of this sentence, thank you, not him!
When the verb is performed on them, they are the object of the sentence: me, you, him, her, it us, them.
Object personal pronouns have something done to them: He hit me.
Unless you're a baby who doesn't know English yet, me does not hit him.
In a case where you would naturally and unabashedly use him or her or them, use me.
Ownership pronouns, also called possessive pronouns, answer the question "Whose?": mine, yours, his, hers, its, ours, theirs. Whose hat is this? Mine.
Unlike nouns, ownership pronouns never use apostrophes to show ownership.
If you cannot tell whether to use a subject or pronoun object, ignore any parts of the sentence that are in the way, and try it out. Your ear will tell if you are right or wrong: You can give the notes to Chris and me/I. You can give the notes to (Chris and) me/I. You can give the notes to me.
