I have created a number of topic specific pages on my Wordpress site. Example: sports, fashion, music, movie, etc.,
I have users who wish to manage the content for each specific page.

Is it possible to assign a Wordpress editor or author page specific privileges so that can create/upload content for a specific page or pages?

You can at the very least set multiple admins. for the account. As each user or author posts or writes content it is posted nd displays under his/her admin. name.

What I am trying to do is grant content providers editor or author permission to a specific page(s) only. I want them to login, upload content and manage their page.
