Answer 1

1) You can not stop users to forward your apk if they have apk in storage, what you can do is to delete it after your app installed(you should search it via some api and if found delete it), Limitation :- apk can be shared before installing.

and there are tools/apps exist in market which claim to convert installed app into apk, and then it can be forwarded to other device.

2) Though you can not stop user to forwarding of your apk, But can stop other user to use it, if they receive this app from other sources then your web, as I myself did it earlier, by client server communication where a key is getting generated on Server based on mobile IMEI, so this app is going to be activated for particular mobile based on IMEI number. hence if other users try to use it you can check if this IMEI is register or not, and take action accordingly.
