Hi @LEARN_IT ,
Do you purchase 5 PowerApps Per App plan license on your side (may be for your Org)?
Actually, when you purchased PowerApps Per App plan license for your account, it would auto-detect how many apps you created in your PowerApps Environment. For PowerApps Per App plan , individual users could only create/run two apps (canvas app or Model-Driven app) at most for a specific business scenario based on the full capabilities of PowerApps.
E.G. If you purchased one PowerApps Per App Plan for your account, you could only create and run two apps at most. If you want to create/run additional apps, you need to purchase additional PowerApps Per App Plan.
Please check the following article for more details:

If you want to run 100 canvas app on your side, you need to purchase 5 PowerApps Per App Plan licenses for your account ($ 10 user/app/month * 5). As an cheaper one, I think the PowerApps Per User plan ($ 40 user/month) would be a better choice for you, and you could create/run unlimited applications (within service limits) based on the full capabilities of PowerApps using PowerApps Per User plan.
Best regards,
