We know that there are a lot more Ga-Matoran in Ga-Koro, but we've only been introduced to a few of them. We don't know the names of any of the others, or what they do.

It's not supposed to be a complete list of Ga-Koro's residents, just the ones we have articles for. And the amount we have is plenty - it's really not that short of a list.
