You've asked a very good question about the weaning of Bengal and other kittens and about their behavior. We would discuss the both in separate paragraphs.
Whether they are Bengal kittens or they are other kitten they have one thing common in them and that is the age of weaning. Almost all types of kittens usually started to wean themselves gradually after the one month of their age.

They gradually improve in their food and started to wean gradually as well. At that time they started to take solid food. After they had started to take solid food they live on that solid food generally but they still suckle from their mother time to time. And this thing continues until they either get maturity or their mother leaves them.

Some mother cats would leave their kittens very early after their weaning as early as after just 3 months while some keep visiting and caring them until their sexual maturity.
Now let's discuss the social behavior of the kittens. Kittens and Bengal kittens both are very highly social animals as compared to other kinds of wild cats. They usually spend their time by interacting with each other after their birth and in their early age. They also keep fighting and keep playing with each other because of their natural social behavior.
I think this information is enough for this question
