no, there is no limit on how many SIM cards a person can own (or be registered to) in Germany. Only if you have hundreds on your name, the provider may check if they are really used by you and are not based on fake registrations. I'm only aware of a SIM card limit per person in Hungary, not in Germany. Some special offers like free SIMs or so may be limited to one or two per offer by the provider.

There is no need to cancel a SIM in Germany. There is also no mechanism in place to transfer a SIM to another name or person. Don't forget that there are still millions of unregistered prepaid SIM cards around as Germany hasn't made any requirement to register them when it introduced mandatory registration of new SIM cards in 2018 unlike Austria right now.
