I've had a look at the linked photographs and... wow, that's a lot of stuff.

If you plan on reconstructing the sets, remember that you can [search for instructions](https://www.lego.com/en-us/service/buildinginstructions) given a set number.

From he above picture I can identify:
- [7156-1 "Corroder"](https://www.bricklink.com/v2/catalog/catalogitem.page?S=7156-1) (which is *not* bionicle but rather Hero Factory) (searched for lime bionicle legs)
- [8696-1 "Bitil"](https://www.bricklink.com/v2/catalog/catalogitem.page?S=8696-1) (searched for yellow bionicle legs with 3 technic holes)
- [8695-1 "Mistika"](https://www.bricklink.com/v2/catalog/catalogitem.page?S=8695-1) (just by combing through list of bionicle sets)

[![disassembled bionicle legs][6]][6]

- Green technic connector with two ball sockets, from [one of four possible sets](https://www.bricklink.com/catalogItemIn.asp?P=50898&colorID=34&in=A). I'm guessing [8914-1 "Toa Mahri Hahli
"](https://www.bricklink.com/v2/catalog/catalogitem.page?S=8914-1) based on the attached dark blue parts, and a mask from a different photograph.
- Clawed feet from aforementioned [8983-1 "Vorox
"](https://www.bricklink.com/v2/catalog/catalogitem.page?S=8983-1), even though the colour doesn't seem to match in the photograph (due to white balance, perhaps?)
