There are different levels of SP chakra, for example, Madara initially only have a derivate by combining its blood with that of Hashirama. Then there is the one awakened by Hagoromo in Naruto and Sasuke. And then there is the complete one, combining all the bijuu's. Kurama, when Sasuke absorbed all bijuu's in the susano, said: his SP chakra is at the level of Hagoromo.

Depending on the level, you can get more skills. And yes, also Nagato has a derivate of SP chakra having the rinnegan's implanted (gets Madara altered cells). All SP moves need SP chakra.

Stop relying on databooks. Yin and Yang in the manga is more like a concept. Like Yin and Yang Kurama divided by Minato. It is the two halfs, Indra and Ashura reunited awakens the SP chakra. Yin and Yang of Indra and Ashura, is not the same Yin and Yang chakras of other minor characters. They have similar properties but it is not the same, other characters can't recreate Hagoromo chakra. Both Naruto and Sasuke have Yin e Yang.
