Help with combine plugins

Hello everyone,

I really need your help. I try to set up a website with the following features:

1. User will sign in with payed subscription (3, 6 or 12 month)
2. Member will get several pages with restrict content.
3. Content consists of several pages (about 10 pages) with “normal” content and some forms, which the user will be able to edit and save.
4. On one page of the restrict content there will be a form, which can be printed and created as pdf and –if possible- published on frontend.
5. Is it possible that each user will get his own e-mail address and account, within the restricted content or within his account?
6. Is it possible that each user will get his own booking calendar?

I will want to create the restrict content with divi theme, so the forms should be inserted as a code in the content.

I thought about wp-members or such, but there I cannot edit the pages.

I really need you help: Can you tell me what plugins to take and can you tell me if an e-mail account and/or booking calendar for each user/member will be possible? I will want to make it as easy as possible, without much coding and without problems with updates…

Thank you so much!!!

Best regards,
Sam
