Is two hours enough time to get from Easy Jet terminal to Air France terminal at CDG for flight back to US?
No
You need to be at check in for the US flight 3 hours ahead -- if you are taking an Easy Jet, I would come in the night before. Easy Jet, if they cancel a flight, won't do anything to get you there. ANd sometimes planes are late. With two separate flights, you really should come in the night before
If you have checked bag(s) to deal with your chances of success look minuscule. ( like 0.000000x%). If you have only carry-on bags the chances are a bit better.
If you cannot get a single ticket for your homeward trek, the advice to get to Paris the day/evening before should be given serious consideration.
