Is it possible to change the reference after order creation

Answer: No it is not.
The point of merchant reference is that it is marked on the order creation. Not where the account last visited or what the last action of that account might have been.

Where can I find the reference of a specific order(s)

The merchant reference can be obtained from the Order API or from the Event order_closed.
