For example because the living room is the size of the two bedrooms combined, I guess it could do with 2 channels, or perhaps one larger one, to match the 2 channels in the bedrooms? And since it's also further from the fresh air source (which would be in the top of the attic) would I use a larger channel to it? I may be overthinking things.

One large diameter channel will give you less noise (and less resistance) than two individual channels. If you can afford (either price- or space-wise) a larger diameter, then go for it! You can later tweak the airflow with an anemostat.
