All speculations, only Nagato has the six path abilities.
Rinnegan absorbs chakra, he said nothing about preta
Gedo mazou is locked up in another dimension, so there is no outerpath.
And deva path? Really?
No banshou tenin or shrina tensei was used or mentioned.
That's nothing but bs. Madara has all six and so does Sasuke.
Rinnegan absorbs chakra through the Pretra Path, one of the Six Paths Jutsu bestowed upon users of the Rinnegan.
In fact, the Manga states that while the people who has transplanted Rinnegan's are given immense power, that the original owner gains far more powers and abilities.
The Outer Path is not the Gedo Mazou. The Outer Path grants the Jutsu, Outer Path โ Samsara of Heavenly Life Technique that revives the dead through the use of the King of Hell. However, this technique may only be available to users who are truly alive themselves, as Madara in his reincarnated state required another living Rinnegan wielder to revive him, and only an authentic Rinnegan may summon the Demonic Statue of the Outer Path.
The Outer Path allows the user to bind and potentially control the movements of those who touch the user's chakra receivers. By implanting the receivers into corpses or reincarnated individuals, the user can control up to six bodies. These bodies, as well as the King of Hell and the creatures summoned through the Animal Path, all have the Rinnegan reflected in their eyes and share visual information with the user through the Outer Path. The user can also manifest the chakra chains of the Demonic Statue to restrict anyone who touches the receivers with an even greater binding power
The Deva Path has
three abilities. Banshou Tenin, Shinra Tensei, and
Chibaku Tensei. Sasuke showed use of Chibaku Tensei, which is a Deva ability, and used Petra Path, which is the Rinnegan's absorption power.
The Rinnegan grants all its users the Six Paths powers, whether or not they use them is entirely up to Kishi.
