Superwall dev rel here. Let me try to help.

Displaying the correct options on the paywall for active subscribers

You can show the correct subscription options based on the user's current plan. There a lot of ways to check that depending on your setup (using a purchase controller, your own logic, superwall delegate, etc) - but you could either make different paywalls depending on the plans, or pass a placement parameter to your paywall to change what shows (I have a YouTube video on that here: https://www.youtube.com/watch?v=7KT9FfKLByA)

when i tried to upgrade/downgrade using paywall it creates multiple active plan in play store instead of upgrade/downgrade plan

Right, if they are in the different subscription groups on the App Store - users can sub to more than one plan by design. I believe Google Play works similarly. Superwall itself doesn’t directly manage subscription upgrades or downgrades — that’s handled by the app stores' billing systems.

Let me know if I can help answer anything else 🚀
