Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi,
You can purchase one Office 365 Business Premium license and install Office on 5 desktops. But it should be all for one user’s use. otherwise, It’s not legal.
You can see the link below, under "license differences" it describes users can install Office 365 ProPlus on up to five different computers with a single Office 365 license.

it means the same user can install and use Office on more than one computer, but multiple users cannot use Office with one account. Each user needs to install their own version.
Let me know if that helps.
Kind Regards,
Engr. Jamshed Muhammad
