Alright, lemme start with the mask powers but please note I don't have time to get the wiki page up. It can take up to an hour to load in its weird offline form right now.
Okay then, I'll see what I got:
Gei-Matoran, or Radiation: Beings of radiation are usually black and dark green with silver armor and masks, and are usually Male. Matoran have the ability to sense extreme or dangerous radiation fields nearby. Toa can absorb, create, and control radiation, which takes form the same as on Earth, and can cause various side effects such as dizziness, sickness, and sometimes death. They can also have limited control over light, as well as infrared and x-ray vision that can severely weaken their elemental energies. Toa are also immune to radiation, as not being so would defeat the purpose of their powers . These Toa are often sought after to become Agents because of their danger to any being without a natural immunity, including Agents. The Radiation sense can also detect Agents nearby, ruining their secrecy. Because of the Agent's efforts, most of the Gei-Toa and Matoran are on Izumal or dead, but a few exist on other planets.
Te-Matoran, or Electronics: The typical color scheme of a being of electronics is varying shades of blue, including translucents, with silver armor, and can be either male or female. The Matoran are usually extremely technically gifted, being able to create any existing invention from a single look, as well as operate it. The Toa can control electronics at a distance. As a Nova Blast, they would release an effect similar to an Earth EMP device. Also a very rare element in the Aethion.
Sta-Matoran, or Rebuff: These strange, exclusive beings are usually colored White and Red, and can be either gender. Instead of having an elemental power, their abilities are with bodies. Matoran have a kind of natural, yet weakened version of the Mask of Healing, while close contact with Toa can increase beings natural Endurance, Strength, Speed, and Mental stimulus, depending on what the Toa decide to use. They can also focus a single trait over long distances to a single being. A Nova Blast would actually have a positive effect, releasing all of these effects to a large area. Due to their nature, these beings are highly sought after as warrior's and leader's assistants, especially on Warzone. On Tribal, they are revered as leaders with godlike powers.
Well, that's my elements I've thought of. I'm not sure about Electronics, since it's kind of the ability of the Mask of Biomechanics, but the others I'm very proud of. And now, just a few masks:
Mask of Solidifying: This mask is considered immoral by most Toa, because of it's ability to temporarily solidify a concentrated area of matter, such as air, water, protodermis, etc. The larger the area, the more energy it takes.
Mask of Scrying: As long as a being wearing this mask could recognize a place, thing, or person, they can "see" that thing in their mind. Very useful for finding things.
Mask of Sense Throwing: Allows a being to project an external eye, ear, nose, mouth, or finger, which is visible to only users of the Elda or Rode. Usually used for spying.
Mask of Strength Distribution: Kind of a hard one to explain, basically it reroutes unused muscle to help in the places with most strain, like for example, transfers strength to legs for running, or arms for melee combat.
Mask of Display: Allows user to project thoughts for others to see.
Mask of Orbit: Causes projectiles thrown at user to orbit around them and can be released all at once at will.
Masks of Solar/Techno-/Bluespace Charge: Allows user to replenish their energies from sunlight (in Core dimension), Electrical sources, or Bluespace.
Mask of Stress: Allows user to locate points of the greatest stress, similar to those Bridge Builder games.
I've thought of a few more, but those are my favorites.
Solidifying -- I'm almost certain we already have one for that, as well as liquefying, etc.
Scrying -- Question, you mean see what is happening with that thing now, right? How much of its surroundings could they see?
Sense Throwing -- Approved!
Strength Distribution -- Approved!
Display -- Isn't this the same thing as Mahiki, illusion?
Orbit -- The name is confusing, but I like the basic power. Something I've thought of myself for my non-Bionicle fiction ironically. Rethink the name though.
Solar/Techno-/Bluespace Charge -- are we talking about three different masks? For the latter, I believe one of the originally established EM masks did that, not sure. If so it could be found in the 100 page guide. If we're talking about one mask, overlap with that might be an issue, plus obviously the name is very clunky.
Stress -- given your description, I think a better name would be Stress Detection, but with that name I approve.
Elements... I'm afraid I don't have an instant "yes" reaction to any of them. I'd need to hear feedback from others.
Radiation is the one closest to an automatic yes, but at this point I don't think we can take on any main elements, so it would have to be a combo (and it could work that way; maybe Light plus Acid or something...).
And rebuff, I don't understand how the name is connected to the description. I'm thinking both this (as Healing) and Electronics/Biomechanics would be better as unusual mutations of Matoran giving them traits based on non-elemental powers, but that's not a final answer.
I do like the description of Rebuff though storywise, more than the other two.
