I think that the AF website is quite clear about arrival lounge at CDG. The only one is in terminal 2C.
Of course, there are many AF lounges in the various terminals, but these are for departures. You can only access them if you have a continuation flight ex-CDG. Once you disembark from 2E and terminate in Paris, you cannot access the departure lounges for security reasons. Similar situation at most airports in the world.
