How can I download apps from Google play that I have already paid for?
Go into playstore, then press the 3 dots for menu and press my apps ---> all and select from the list of apps that you've had installed previously.
you can recover access to these apps by simply switching the account you’re currently signed into on Google Play.
Your application purchases are tied to your Google Account and can be installed an unlimited amount of times on any device. So, for example, if you remove "My Favorite Game" to save memory, you can reinstall it at a later date with no charge by simply visiting My Apps. You can also re-install apps from play.google.com from the My Android Apps section.
