What level and wp membership access level should I set for my site?


I am figuring out how the best to carry out the following.
Please look at the image I attached.
1. I am at a lost creating the required levels for my requirements.
Furthermore, WP has some default access levels like admin, editor, subscriber etc.
Do I need to adjust the WP levels when I am creating my own levels using Pro Sites?

Will appreciate any help that come!
