Were Mata Nui Matoran revived?

Hello Greg!
In MNOG, it is noted that several Matoran perished to the forces of Makuta. From what I can remember off the top of my head, a group of Ta-Koro guard members perished in Ko-Wahi.

Are these deaths canon? And if so, were these Matoran revived on the Red Star, considering Jaller was supposedly almost revived while he was on Mata Nui?
