Hi There,
In order to install the applications that you have purchased under the Creative Cloud for teams, you can either create packages using the Admin Console and then deploy these packages if you have a deployment system in place or you can just assign the licenses to your users on the Admin Console and if they have administrator rights on their machines, they can install the applications themselves from the Adobe website.
To answer your second question, under named user licensing, the application entitlements are tied to the users' email addresses so each student/staff would need the licenses assigned to a unique email address. To learn more about how named-user licensing works, please refer to the following URL:
