Can I select who can see each form submissions?

I want only for one of my teammates to receive submits from "Form A", and an other team meat to see submissions from "Form B", so not everybody can see every submission.

Both of your teammates can create JotForm account and you can add them as sub account users of your account. You can then share submissions of the "Form A" with one teammate and submissions of the "Form B" with other. Inside of this guide you can find share forms with sub account user:

In case that you want to send email Notification of the"Form A" to one teammate and email Notification of the "Form B" to other teammate, then you can set email address of first teammate as recipient email address of "Form A" and email address of second teammate as recipient email address of the "Form B".
