Different Exclusive Content

I still have to install the plugin since my page is under construction but I want to bring me ahead.
Is it possible to create different pages that are exclusive to different users?
I’ll explain it better.
Let’s say that I have 5 video courses, that I’m selling.
Each video is on a different page on the website.
User “A” is interested in buying the 3rd video. He log to that page, pays, and unlock the content. But the other videos, even if he’s logged are still locked. Is it possible? can I have create 5 different groups and enable each group to see content from each page, so that if someone register to a page/group can see only that content?
Thanks in advance.
