Hi Team, could someone help me understand how many users are allowed to access the Creative Cloud products if I purchase Creative Cloud plan, and where I can find the usage report for my Creative Cloud subscription?

you need a teams or enterprise license to assign more than one user.

Cloud License allows 2 activations at a time http://www.adobe.com/legal/licenses-terms.html
-you may use on ONE computer at a time, and you may NOT share your subscription

-Windows or Mac does not matter... 2 on the same operating system, or 1 on each

If you want to provide subscriptions for employees you need  TEAM subscription, where you buy a subscription for each employee
