I'm currently playing wiht Bluetooth Low Energy for android 4.3, don't have BLE beacons at the moment, so my idea is to user one android 4.3 as BLE server. But there is quite good explanation how to create client app
http://developer.android.com/guide/topics/connectivity/bluetooth-le.html#close
and almost nothing about server, except this link http://developer.android.com/reference/android/bluetooth/BluetoothGattServer.html
Is there are some tutorials or examples?
I found those very useful:

For the server parh check out this example:

I want to develop a real-time application over the internet. This means I need a fast communication between clients (Android).
Which protocol should I use? Should I use a base server to support the communication between the single clients?
And please don't forget that everything should work over the internet (NOT in the same LAN).
Can you recommend some Java Frameworks?
you can use Firebase Cloud Message for android, check this page:
https://firebase.google.com/docs/
and this link:
https://firebase.google.com/docs/samples/
you should be interested in realtime database

The S7 got a whole lot of new functions. Heart Rate Monitor, Always-On-Screen, where can I find worthful references or informtation about the API to be used to use these features?
The Heart Rate Monitor functions can be found in the Sensor Extension SDK. I think the Always On mode is only available for selected Samsung apps. It cannot be used by third-party apps.

Is there an API to somehow tell me when another application tries to make use of the Internet? ... Or how else may I implement this?

Not really. You can use TrafficStats to determine bandwidth consumption, but you would have to poll that data.
