To answer the OP - yes there is. Search in the Reference collection or WOJ.
Initially Jim said that Archangels and the Faerie Queens and Gods were of the same level. This was established in the early books but has essentially been retconned. TWG/Almighty is considered the top of the food chain (though what exactly it is has not been explained). Archangel are the tier below that (Jim called them VP's of Creation - these days in corporate they would more likely be SVPs and Officers, but I will get into that in a second). Archangels have been said to have the power to annihilate galaxies with their thoughts, take apart all the worlds everywhere etc. This is both WOJ and in the later novels. A particular Archangel (the Prince of Darkness) has been called an "officer" of Hell. This was met with some confusion by fans when Hades (the god) is considered the CEO of his own little company, but Lucifer is an Officer. In current corporate lingo, an officer is generally one of the highest executive positions (and includes the CEO, and sometimes Chair and/or President - the terms generally amount to the same thing). This resolves the confusion somewhat, that as a senior Archangel Lucifer is up the top, but as we don't know much about Hell or how it functions or it's purpose, we cannot understand why Lucifer might not be the Chairman. My guess is technically TWG is Chairman as Hell serves a purpose, and as constantly stated around the books, Power has Purpose.
Of note, recently we discovered that the Walker He Who Walks Behind is considered on the same level as an Archangel. This was odd as the other Walker, He Who Walks Before, was considered as "big as Mab, but unimaginably deeper". This suggests we don't fully understand how the Power levels really work yet.
The Mothers are also considered as high as Archangels, and have been described as orders of magnitude greater than the Queens.
The next level are Gods, Queens, Dragons, Angels, Fallen. Depending on how much they are involved depends where they fall but it is clear from WOJ that just because you have more brute force, doesn't mean you have more influence or are more deadly. Often the inverse is true. Compare Vadderung/Kringle and Hades. Hades might well have more muscle these days, Vadderung has seemingly sacrificed much of his former Power to retain influence in the world. On the other hand, his influence seems much more pervasive and dangerous comparatively. Drakul, Ferrovax and the council of Black Court Elders are on this level. Also to some degree, the Lords of the Outer Night. Various demons and Outsiders exist here and below.
The Leansidhe, Eldest Gruff, the Erlking and Kringle are the next level. I would say that Mouse when in the Carpenter's home and Ivy fall in somewhere around here. I put Kringle here as Vadderung's power and influence jumps around - he sits on a few levels depending on the mask he wears I suspect.
Below them is the Ladies and possible OG Merlin and perhaps Morganna Le Fay, maybe Kemmler. I would hazard that the Ladies have more brute force because of what they represent, but not necessarily more influential than the others. OG Naagloshii.
The Senior Council types and some others are probably next - maybe some of the Bigfoot types. The Cantrev Lords of the Formor are also somewhere here. Regular Skinwalkers.
Finally regular Wizards, fae etc.
Vanilla mortals - which as JB keeps stressing, should not be mistaken for harmless, especially when massed, planned, well researched and angry. We did invent nukes after all.
Side note - The Old Ones (possibly the Old Gods - there is some confusion on this) who a race of demon gods that ruled the Earth and were banished or locked away and rule the Outsiders, are not included in this list. That is because we know almost nothing about them. Bob mentioned they could cross a threshold and do all kinds of damage - which was considered pretty bad, he also compared them to a big old god. I suspect that en masse they could well challenge TWG himself. Why? Because of a little known WOJ. In it, he describes that Lucifer is nowhere near the biggest bad on the tree for the simple fact that he is FOR REALITY. Lucifer is having an existential argument with TWG that we can only vaguely grasp. But it seems his is Team Reality. The Old Ones wish for no more reality it seems. Which is why Jim considers Nicodemus more dangerous to reality than Lucifer, in some ways. Both Vadderung and the Mothers have described the twin events of the prisoners of Demonreach getting free and the Outsiders breaking through the gate as not merely catastrophic, but the end (or "everything stops. everything" as Mother Summer put it). The term Empty Night seems to be a big hint, as has been thrown around a few times in the series.
Hope that helps
