Hi @nagarjunakan ,
1. We create reports on the desktop and publish them to power Bi services. At this time, users will not be able to contact other reports or delete datasets. In addition, there will be a backup of pbix file on our local desktop. However, there are some limitations.
Check this link:
powerbi-desktop-report-lifecycle-datasets.
2. After adding a new tenant, there is no impact from the power Bi license ID to the end user
3. For deleting a license, you can delete it in Microsoft 365 admin center. View this link:

For adding licenses, you can add or purchase them in azure portal or Microsoft 365 admin center. You can view this link:
