Paying the police fine while the loan is settled with the bank

I had AED 120,000 personal loan + 20,000 interest out of which I paid AED 100,000 till last May 2020.

I was out of UAE due to transplant surgery and was unable to go back due to the Covid situation, meanwhile, in July 2020, the bank deposited my security cheque of AED 120,000 & it bounced.

For the past 1.5 years, I am without a job or income. I am trying to reach a settlement with the bank to clear the cheque bounce case.

My questions are:

1) If the bank agrees to a settlement and, after payment, withdraws the cheque bounce case, should I still pay the police fine?

2) While entering the UAE, will I have any problem after settlement?

3) What are all documents that I should request from the bank before & after settlement?

4) I have AED 40,000 outstanding on a personal loan, requesting the bank for a one-time settlement of AED 20,000. Can any law firm help/assist me with that?
