Do they send RFE's for all forms in one envelope?

I know it might sound silly, but I just received an RFE for my I-864. I just sent it out today and now I am very anxious, thinking that they might find more things that's missing. That RFE caught me off guard cause I double checked and was sure I submitted everything that needed to be submitted.

So if anything else was missing, they should have sent it with that request, right?

Absolutely! Several questions are placed in one envelope; but that doesn't mean you wouldn't get another. Yet, most likely Not.
