5000 limit is applicable to all intrastate inward supplies from UNREGISTERED DEALERS only. But you have to see this limit in aggregate for a particular day. In your case I guess transportation and CA fees may attract reverse charge if the payment exceeds 5000 in a day. For bank charges, Reverse Charge may not be applicable as almost all the banks are registered under GST. And accountant salary will also not attract reverse charge as it is a salary payment to an employee.
