There's no such thing as "having" all 5 natures only "knowing how to use", because EVERYONE has all 5 natures. Chakra can be transformed into any of them, the user just has to have skill and knowledge to do so, it requires no special genetics or ability besides training. The Rinnegan can't give natures. It only allows one to master them faster.
