Most of these, I have no idea, but there are a few that have been answered.




We know that Rand is strong in all five powers, yes. We know that Egwene is strong with earth and fire(for the creation of cuendillar). She says at some point she is strong in air and water. And she has demonstrated a degree of strength in spirit(stilling that black ajah with ease way back in tear, and she would be a good deal stronger now, etc). So probably.



We know that men develop their strength much faster than women. We also know that Egwene is ahead of Elayne and Nynaeve in her development(though Nynaeve is stronger just because her potential is so much higher). So Elayne and Nynaeve are definately not at their max. Egwene might or might not be. Rand also might or might not be.




We know that it does not. Demandred is weaker than only to Ishy and Aginor among the men, but is listed seventh.



There isn't any special automatic success of thirteen aes sedai shielding someone just because there are 13 of them. its just that the 13 weakest aes sedai(since you have to be of at least decent strength to be able to be raised to Aes Sedai) are stronger than the strongest man. Thirteen women of Morgase's strength in a circle (assuming she can link) couldn't shield Rand with no angreal, much less with a sa'angreal.

This has been discussed at some point, Brandon was just apparently unaware of it at the time.



RJ left a list of the order of strength of the male channelers, and a separate one for the order of the strength of the female channelers. Apparently there was not much detail on exactly what the difference between the various levels of power was, just that aes sedai A was more powerful than Aes Sedai B, who was more powerful than Aes Sedai C. So we know who is more powerful than who, but not really how much (or at least Brandon does...we know for many of them, but not all).




Graendal is probably stronger than Semirhage. Graendal implies, but does not state that Lanfear was the only female forsaken stronger than her.



There is no comparison made between the saidar rankings and saidin rankings. However, although men are much stronger than women in general, women are more dexterous with their weavings, so it comes out about even in a duel. So given that Asmodean was at the very bottom of the male forsaken rankings, while Lanfear was at the very top of the female forsaken rankings, while he might or might not have been able to hold more saidin than she could hold saidar, she almost certainly could defeat him with relative ease.



We know that Nynaeve is much stronger than Egwene. And Nynaeve is only slightly stronger than Moghedien, so Moghedien is almost certainly still much stronger than Egwene.



Moghedien is the weakest of the female forsaken, so Mesaana would be stronger. How much, we don't know.



Lanfear at least was almost certainly stronger than Sharina's potential. Sharina is described as "ahead" of Nynaeve, but not "well ahead" Lanfear, on the other hand, is much stronger than Moghedien, who is only a little weaker than Nynaeve. These are all relative comparisons, so you can't say for certain, but Sharina is probably weaker than Lanfear, and maybe even Cyndane, though not much. Probably on around the same level as Graendal, who is a little weaker than Cyndane.
