I really don't know what you expect. Or what examples would have done. Like with "sie", these words only differ by the verb that follows (and even then not always). Although I should correct that "ihr" - the form of address - is actually the informal, familiar, and always plural form. "Sie" takes care of all the formal options.

...Oh, my sources of examples refuse to work at the moment... Well, I'm gonna try to come up with something, but, well, they're going to be these words + verbs in conjugations, which I don't know how well you know yet... And sometimes they're going to change depending on the case and gender...

Ihr springt. - You jump. (Or "Y'all jump", as some grammarians like to differentiate it.)

Ihre Katze isst. - Her cat is eating. (Or, indeed, "Their cat is eating.")

Die Menschen bewegen ihre Beine. - The people are moving their legs. ("Her" really wouldn't make any sense here.)

...And "mein" - especially "meinen", "meinem", and "meiner" - is going to be pretty tough to sort out, without a solid grounding in cases and when they are used. I mean, "Ich gebe meinem Hund ein Spielzeug". - "I give my dog a toy." Does it really make things clearer?

Maybe it is a problem with the book. But at the same time it seems to be a chicken and egg problem. I mean, language is a pretty interconnected thing. Like in my examples, you start illustrating pronouns - you step into cases and conjugations. And genders.
