I think, you are referring adding two subusers under your main account.
As I checked your account, you are in a free plan and it is allowed to add only 1 subuser to free plans. If you would like to add 2 users, you need to upgrade your account one of paid plan. You can also check it form your billing page.
This is valid for your account, the subusers do not need to upgrade their account to be your subuser. On the other hand, they must have a jotform account.
Here is the guide where you can find more details about subuser feature.
