1. I don't know. Did you search
http://plugins.cordova.io?
2. Yes. Though I'm not familiar enough with how that would work to tell you where to start. Sorry. :-(
3. No. iOS does not permit any app to overlay another in the manner of Facebook Messenger. In fact, FB Messenger doesn't even get to do this on iOS. Furthermore, please don't do this on Android -- it's a horrible end-user experience because inevitably you will cover something up that the user needs to interact with.
