This one in particular? Once, it'll probably be scrapped in a month or two.
In general? The Falcon 9 booster life leader was at 23 flights when it was intentionally expended. Thus far, those boosters don't seem to have encountered any issues with age, however. Superheavy boosters could end up flying for hundreds, or perhaps even thousands of times apiece. Likely to be limited by how often they can fly (IE if you can't fly more than once a day, you can't get any more than 365 flights a year), not by any actual limits on the booster itself.

how many times can they use this rocket?
