Borrowers Defense – Couple Questions

I am sorry to bother and everyone keeps pointing me in a hundred directions to read tons of info that doesn’t state it clearly what I should do, if anything. I have 3 main questions.

1) My loans that were not consolidated were discharged already but the others that are consolidated, were NOT discharged. I only ever went to one school (Ai), for one degree. Do I need to do something like unconsolidate them to get it to work? If that is a thing?

2) My best friend who went to school with me got a refund back on her loan but I haven’t gotten anything back on mine. Do I need to do something to get money back?

3) While in school my dad took out a parent plus for me. He submitted a Borrowers Defense but they told him recently by mail that he will have to start paying it back again but shouldn’t he be in the same class as me? They sent him a letter awhile ago saying his had been approved or whatever for discharge so we are both confused.

Thanks!
