do the choices below to alotted seat in 1st round considered for 2nd round if i choose FLOAT option in josaa counselling
No, the choices below to an allotted seat are never considered in any case. Once you have got a seat, you can only move above in your preference list not below. Float option means that you have accepted the seat you have been given but you will change if a better seat in better college is offered, it does not mean you can go down on your preference list. That is why it is important to correctly optimize your preference list before locking the choices.
