My analysis, based on observation:

Six Paths Senjutsu represents the "physical" power of the Sage of Six Paths, as opposed to the Rinnegan which represents his "mental" power. It seems to be characterized by the marking of a single rinne and nine tomoe on the user's back, as well as the manifestation of the Truthseeker Orbs, as seen with Obito, Madara, and Naruto. This particular "Sage Mode" transformation seems to draw its Natural Energy passively from the Jinchuuriki's Biju.

Obito and Madara underwent physical transformations, whereas Naruto's transformation seems to extend only to his chakra cloak. This may be because Obito and Madara became host to the Juubi including its physical form (the Gedo Statue), while Naruto only became host to the chakra of the nine Biju.

I believe that the Truthseeker Orbs are likely a simultaneous combination of all chakra natures, infused and manipulated with Natural Energy in the same way that Naruto used Senjutsu to safely wield and throw his Rasenshuriken -- hence the limited range of control. The Truthseeker Orbs are also passively generated and are essentially "always active," causing them to behave more like tools, which can be discarded or lost.

I believe that Naruto should be listed as a Lava Release and Magnet Release user (he is, after all, using these techniques), it just needs to be noted that these are Tailed Beast Skills, not Kekkei Genkai (same as with Roshi).

Also, may be worth noting that in Viz's translation, Madara specifically identifies Sasuke's new eye as the "one-eyed Rinnegan," which may have intended signifigance beyond him only gaining one Rinnegan, as Kaguya's single Sharingan also transformed into a sort of "one-eyed" Rinnegan. So it might be that "One-Eyed Rinnegan" refers to a specific type of Rinnegan.
