Dude I think you need to do a little research. I am typing this to you on my M1 Max with 4 monitors…2 of them are at 144hz
A cursory Google search will show you that a lot of the information you threw up there is incorrect. It does seem you’re right about the air m2 model supporting only 1. However the M3 MbAir supports 2 so definitely not the case that all base Mx models support 1. Just the M1 and M2 base chip airs, and who is buying a base model M1 air in 2024? Way too long in the tooth. So functionally it’s 1 single model they have listed.
