Microsite with different admin access

Dear support,

I would like to create a wordpress site. Inside my main website, I would like to have some different page/microsite that allow only specific admin to access and change their content. Can wordpress do this?

Example:

I want to create a food junction website. Inside this website I will create many pages that allow different owner of the food store to access and edit their own page about their own food. Each owner can’t edit other’s owner’s page.

Is WordPress possible to do this? I have some knowledge on html and css.

Hope to heard from you all soon… Thanks
