BTC divided to BTC and BCC, and will be divided to BTG and B2X.
1. B2X will become real bitcoin?
2. More BT* will appear in future?
How did you able to calculate such thing? Bitcoin would be always the real bitcoin no matter what and those coins being created on forks are just another altcoin in the market. Try to look at on BCH what happen? It didnt really get the same support just like we saw on bitcoin itself therefore theres no point on comparing it in to those altcoins.
The market will decide ultimately. And futures are not looking good for Segwit2x:

When you think you are receiving free money, you are not considering that if the network wasn't attacked by contentions hardforkers, the price would be much higher than it is now, so ultimately you don't gain anything, other than wasting your time to get some extra BTC by dumping the fork.
