In general Air France recommends 2-3h connection time at CDG at all its flights, with a minimum connection time of 1h. For example, 2E and 2F, although being the 2 Terminal, are two different islands which requieres a long walk and security control. If you´re lucky, your plane arrives on time, few people in front of security control and you don´t carry much luggage to run along the gates, it is reasonalbe you make it, however if obstacles appear....
All signs at the airport are in English and French and many employees at the airport speak English, so indications are clear.
We recommend not too tight flight schedules, just to be on the safe side and having relaxed flights.
Have a good flight,
