Can i use the RER B ticket (from CDG Airport to Chatelet Les Helles) to transfer to RER A (from Chatelet Les Helles to Gare De Lyon).

Yes, you can use RER Tickets to transfer from RER B to RER A inside of central Paris such as at Chatelet Les Halles (for Gare de Lyon).
This will work for RER Tickets from CDG.
