IMO if these activities are not impacting on the child’s schoolwork or sleep/ downtime , then there may not be a problem. If the child enjoys all these activities and is not just doing them cause they are being made to do them, then this can only be a good thing But if time is an issue or any of the other caveats I have mentioned above exist, then choose the ones the child likes the best and settle on a few of them It also depends on the child’s age as well.
