Many of the above stones belong to the same category. Some are not stones but minerals that can be made into gemstones, not wetstones, and some others are the same stone.
The stones that could belong in the hones category are so many, if you tried to find each one of them from a different region, the list alone would be a big book, without counting the stones that have yet to be discovered, or have been destroyed for something that exists below them, like Coal, Gold Uranium, Silver etc. For the ones we already know, I'm pretty sure they are less than 0.1% of the stones that still exist on earth waiting to be found.
In the Ardennes meeting, Andre, the geologist told us that in Iran there are Jnats without the J. The exact same stones, with the exact same characteristics, honing capabilities, soft and hard, they even have the characteristic skin. Who knew about that in the whole SRP? There are also coticule veins in Africa, the known coticule.
Here in Greece we are only using the Cretan stone, but we have more than a dozen of quality hones, from bevel setters to finishers, and almost every small area has its own varieties. A year ago I visited the island of Limnos, the whole island was a hone. If you picked up a random stone there, you would find it to be a sharpening stone, again, from somewhat coarse sandstones up to very fine, very hard finishers. And we know about a few famous stones, every European country has its own signature hone. How about Africa? Asia? and I bet there are thousands of different high grade hones both in Africa and in Asia we still don't know, and probably never will. Or America? I'm sure you know it's not just about the Arkansas stones and the ones similar to them.
The hone's world is vast and diverse. The 6 types of stones you are referring to above is a bacterium on the tip of the iceberg.

I believe you need to do some more research on the Japanese stones, for example Shinden was a mine and not a type of stone.

From So-San's site, there are about 80 strata in the Japanese naori, and nine distinct types of stone:

Aka-pin
Tenjyou siuta
Hachmai
Senmai
Tomae
Aisa
Namito
Honsuita
Shiro suita

Japan Tool - Technique&Knowledge - Awasedo

And from an old Knifeforums post by pur own Stefan, 10 types of Mikawa Nagura:

Mejiro
Tenjou
Buchikou
Koma
Botan
Layered Botan
Mushi
Atsu
Ban
Shikiban

And the Tsushima or kuro (black) nagura

There are also nagura from Gifu which I understand is the same formation as the Mikawa naguras but ungraded and from a neighboring province. There's also Chu nagura that isn't part of this formation.

I don't know how precise a list you're trying to make, but you might just want to reference Mikawa, Tsushima, Chu, and Gifu naguras - and there could well be more.

There are also some uncommon coarser stones that crop up from time to time, Ikarishi, aoto, saeki-to, etc.

I've found that if you electrically charge the FrankenPHIG you get better edges....
