Can sub-users create forms under my account?

Yes, when you set up a sub-user it will be allowed to create forms  under your account so it means that the limits of your account/the main account will be applied to the forms  the sub-user creates. 

I would suggest you to take a look on this guide so you can get the steps to set up a sub-user account: https://www.jotform.com/help/232-How-to-share-forms-with-a-sub-account-user
