Different size intake and return lines.

Hi guys and gals, Just finalizing some stuff for my pool plumbing. I am running 2 inch pipe for my intake. Main drain and Skimmer, but was wondering if I should use 1.5" for my 3 returns? Or should it all be 2"? These are all home runs.

1.5" is fine. You need to come down to 1.5" returns at the pool for standard eyeball fittings. So it becomes 1.5" sooner or later.

Do the equipment plumbing 2".
