Yes, every planet up to Saturn rules over a specific chakra.

Jupiter, Venus and Mercury do co-rulerships and dual rulerships between chakras (heart-throat for Venus and Mercury, with Mercury presiding over the Anahata and Venus moreso over Vishuddi. Jupiter rules the Crown chakra but also rules functions of the Pineal gland pertaining to masculine features of the right side of it, and thus also has a sub-connection to the Pineal 6th chakra as well.
Note- I believe Mercury on top of the Heart and Throat, also has a connection to the Solar Plexus chakra, particularly because of the numerology surrounding both and also involving relevant colours. If anyone has any insight here it would be much appreciated.*
The other planets up to Saturn are straightforward and are only connected to one chakra. Saturn being the top of the list as our closest naked-eye planet is an intriguing coincidence in itself as Saturn rules the 10th sign which breaks down to 1 as in the 1st chakra it's rulership. It being the closest planet of the naked-eye and why the ancients regarded it as the furthest outlying planet is poetic for the planet's associations with restriction, blindness and delay. The next planet we discovered was Uranus which was to the contrary, ruling freedom, higher awareness and technology-hence the changes of the times. I love the astrological poetry of that.
As for Rahu and Ketu they are still elusive towards my personal knowledge, but I second the notion that they are to do with fate and karma based on what experience I have had studying them. They correlate with Azazel's and Saurashtra's "opener and closer" theme within their respective interpretations from what I've read and understood about them on the general level. They are Plutonian and also relate in lexis generally to the ideas implied by the Black Sun, Nigredo etc. The never ceasing flow of time and the constant undoing of things good or bad, proud or insignificant or implicitly life or death- as in rebirth. I also have an inkling that it may relate to the True Lilith point in some way, as it is dependent on the Moon no? I discovered recently that the True Lilith point was literally an unseen secondary point of orbit for the Moon which blew my mind, perhaps it could also explain the Moon's nodes?
Hope you find out what you're after brother.
