I have accidentally opened and started 5 forms

Didn't realise when I was looking through each form to decide which would be the best one to use that I had opened them and now have used the full amount available to me? Is there anyway that I can change this?

You may simply delete the forms in order to free up the limit, this guide will help you doing so: https://www.jotform.com/help/377-How-to-Delete-Form-Submission-Data
