Do we have any canon info that might indicate a time-range?
I'd imagine there'd be a distribution in the times that specific Matoran, not just Ga-Matoran, could hold their breaths for, as evidenced by Taipu being stronger than other Onu-Matoran. Presumably it's variation in organic components which can be trained, and we know that Toa and Matoran have organic lungs so it's plausible.
I also remember reading that someone here got the impression that regular Matoran could hold their breaths for a bit longer than humans. I don't know about those sources per se, but if anyone knows any please let us know.
It seems that the average time a human adult can hold their breath is somewhere between 1-2 minutes (a quick look didn't yield a more specific number, but it's probably out there for anyone who wants to search more). It seems like most people can fairly reliably train to go to like 4-5 minutes, pro divers can usually do like 10, and the current World Record is astonishing 22 minutes and 22 seconds set by German freediver Tom Sietas in 2012.
My current headcanon on time ranges is:
3 min for average Matoran / Toa
15 min for average Ga-Matoran / Ga-Toa
30-40 min for trained Ga-Matoran / Ga-Toa, i.e. fisherwomen etc.
1hr as the extreme pinnacle of what Ga-Matoran / Toa can do.
Obviously all of these times go down if the diver is having to do any form of exercise.
I'd love to read your thoughts on the matter, and any canon evidence you can bring forward
