7 natures. 5 basic natures, yin, and yang.

Chapter 68, Chapter 577, and Boruto episode 24(the ladder 2 being the two more recent references) prove that a character only needs the potential to perform an ability.

The wiki doesnt even have reference for the claim that a Sharingan user needs to already know a nature release to perform a jutsu of said release. And it directly refutes the manga.
