Hello PQ123,
You'll first need to sign out of iMessage for the Apple ID that was signed into the device previously. You'll then need to sign in with your Apple ID: Set up Messages on iPhone - Apple Support
Concerning those third party apps, you'll want to reach out to the developers: How to contact an app developer - Apple Support They'd be in the best position to provide more details on their particular apps.
Take care.
