My organization has an upgraded jotform account and has me as a sub-use

My organization has an upgraded jotform account and has me as a sub-user so I am able to see their shared folders. So my question is, am I able to use my 1 invitation to invite a co-worker to be a sub-user under me and would they be able to see the parent directory of my organization?

Yes, try setting up the sub user and see how the forms are listed, here is a guide that will help you adding the sub user: https://www.jotform.com/help/232-How-to-Share-Forms-with-a-Sub-Account-User 

Thanks.
