If your aadhar card has an incorrect spelling of your father's name, you can get it corrected and the time extended for making corrections in the aadhar card is for another 3 months.
The PAN card also can be corrected subsequently
The name given in the bank account and the post office account need not be changed for now, you can get it corrected when you are opening a new account in future.
Your educational certificates have the proper name hence you need not be worried on that count too.
