Answer 1

You can set badge value in (notification payload). You can use your own server to send push notifications and control (increment) a badge value. There is no way to control badge number if you are sending a push notification directly from device to device with Firebase. The only way you can set a badge is when you are sure the destination device will receive only push notifications from one source device, and you can set a badge value on that source device.
