Also, not sure if you are aware of this but, the Google Play Store, also has a website - https://www.play.google.com
that you can use to install apps onto your many android devices. If you use the same account, what you would do is logon and then select the app(s) that you want to install, once you select to install the app, it will ask you which device you want to install the app to and it will only install to that device and not all of them, however, you can also still choose to install the same app to multiple devices from here also, if the app is compatible with your device. It actually pushes the software to your device(s) wirelessly & "automagically". Hope this helps!!!!
