HELP. My sister just refinanced and the paper work has many fees.?

My sister just refinanced her home. She regrets doing it. There are too many fees. We don’t even know what they mean. For example:
-BROKER APPRAISAL FEE: $ 450.00
-BROKER PROCESSING FEE: $ 695.00
-LENDER LOAN FEE TO BROKER: $ 6200.00
-BROKER ORIGINATION FEE: $ 3100.00
-FUNDING AND REVIEW: $ 455.00
these are just the ridiculous looking ones.
The proposed loan amount is 310,000.00

The screwed up part is, the mortgage broker (a good friend of ours) said she wasn’t going to charge us for preparing it.
Is there any way this can be reversed? This was processed march 29.
