Wrongly transferred to huf dormant account ?

More than the law, this  is an issue of procedure.

Is there any rule that all the members of the HUF need to give consent to bank directly to activate the dormant account, whether the application singed and submitted by the Karta is not enough?

Since HUF is not a real person and cannot sign on its own behalf, a rubber stamp with Karta’s signature in the applciaiton form to activate the dormant account will be sufficient, you can inform the bank in this regard and ask the karta to submit an application to activate the dormant account after which he can transfer the  amount which was wrongly remitted to his HUF by you.
