Hi @AmitLoh-Powerap,
If they are the accounts which are under the same organization, then we could manage the User Account and Passwords under Office 365 Admin Center, with no Office 365 Licenses assigned.
For the users which is out of the organization, currently sharing apps with external users is not available under PowerApps.
Reference:
Idea: Opening for using the app outside your domain
In addition, ADFS is supported when signin with PowerApps.
Please check the article below for more information regarding PowerApps Licensing:
If you have any further questions, please feel free to post back.
Regards
