As I read more Japanese texts, I’m finding there are a lot of ways to say “us.” Are there any contextual differences or differences in politeness level between 僕等, 我々, 僕たち, and お互い?

俺たち、僕たち、私たち、わたくしたち have the politeness level differences of the corresponding words without -たち. – mic Jan 21 at 15:04
They have a different nuance, and お互い doesn't mean "us" but "each other".
僕たち and 僕等 are almost the same, I feel 僕等 is a bit casual. 我々 is a bit exaggerated, so it is not often used in daily conversation but in lofty and exaggerated speeches.
