I have an app with 2 app extensions. I have set all 3 of them up as an App Group. Each of them have a separate app and bundle ID. Now, when I submit the app on iTC, do I submit 3 apps; i.e.build each target separately, generating 3 .ipa files and then bundle them up on iTC? Or is it OK to compile everything(all 3 targets) in 1 bundle and just submit 1 .ipa file?
How to submit App Group on iTC?

You can only compile/build from one target per app at one time.
If you want to sell them as a bundle, upload them as three apps, then create a bundle via iTunes Connect - or - build one app that contain the functionality of all three, assuming that makes sense for the user, and upload it.
