Drive train issue
 

When roll 2 front wheels to the same direction, 2 rear wheels roll the same direction . That is normal. But roll 2 rear wheels, one of front wheels rolls but another front wheel stop and doesn't roll. How to fix it?

Front and rear left wheel roll a direction, right wheel roll opposite direction. so diff. works fine.

It's normal. Unless you have locked front diffs then both front should roll.

works fine now after running on the ground for 10 mins

It's normal. Has to do with the front differential splitting the power when the tires are free wheeling in the air. The tire with the least resistance moves, due to the differential doing it's job (letting the wheels move at independent speeds).
