Kishi hasn't made the doujutsu situation any easier... we have:
 * We have Byakugan = apparently was an Otsutsuki thing even before Chakra Fruits
 * We have Tenseigan = unexplained
 * We have Rinne Sharingan = apparently result of Kaguya having eaten Earth Shinju's chakra fruit
 * We have red Rinnegan
 * We have ordinary Rinnegan
 * We have Rinnegan with tomoe, having Sharingan powers

In my opinion Byakugan is Otsutsuki's natural eyes, genetic part of all of them, not really a Kekkei 'something' from their point of view.

Tenseigan in my opinion is a result of 'PURE' Byakugan + Six Paths Sage Chakra. In The Last novel it's stated that the Tenseigan has to do with Natural Energy and it also enabled Toneri to use Truth Seeking Balls, which consist of all natures and are Senjutsu, hence I think that the Tenseigan is Pure/Flawless/Perfect Byakugan + Six Paths Sage Chakra/Senjutsu.

Rinne Sharingan in my opinion is the ultimate/prime form of the Sharingan-Rinnegan line.

Rinnegan and Sharingan are less than Rinne Sharingan and in my opinion splits of its power.

Red Rinnegan? No idea, but it later turned normal color, so maybe it wasn't fully complete Rinnegan at first.

In my opinion Sasuke's tomoe Rinnegan while still being a Rinnegan, it also having Sharingan powers I would say means, that it's in-between stage from Rinnegan and Rinne Sharingan.
