You need to ask yourself the right question. It isn't one or many sequences, the question is do these sequences need to be sequential or not on any of the tables. Depending on the workload, one may suffice if they do not need to be relatively sequential. If it is a heavy workload, you may need one for each regardless of the need to be sequential.
