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 given a set number.
From he above picture I can identify:
- 7156-1 "Corroder" (which is not bionicle but rather Hero Factory) (searched for lime bionicle legs)
- 8696-1 "Bitil" (searched for yellow bionicle legs with 3 technic holes)
- 8695-1 "Mistika" (just by combing through list of bionicle sets)
- 8622-1 "Nidhiki" (dark green 7+3 liftarm)
- 8727-1 "Inika Toa Jaller " (pearl gold bionicle chest)
- 8983-1 "Vorox " (tan bionicle leg)
- Bits of 8533-1 "Gali" (medium blue bionicle parts)
- Some unknown Mega Blocks blue&white robot/figure at toe bottom right. Note the "mega blocks" markings in the center of groups of four studs.
- Yellow parts possible part of aforementioned 8696-1 "Bitil"
- Lots of unknown parts
- Green technic connector with two ball sockets, from one of four possible sets. I'm guessing 8914-1 "Toa Mahri Hahli " based on the attached dark blue parts, and a mask from a different photograph.
- Clawed feet from aforementioned 8983-1 "Vorox ", even though the colour doesn't seem to match in the photograph (due to white balance, perhaps?)
