How to control two servo motor each with a potentiometer controlled wirlessly through NRF24L01 and Arduino uno?

No I will not crosscheck. What is your aim?

  1. beeing dependend for all and any small code-modification to ask again in the forum?
    or
  2. learning how it works and beeing able to modify your code yourself?

The second option still includes to ask all kinds of questions in the forum but you should show some more own effort in writing your code.

The microcontrollerworld is not superstandardised like USB-devices.
You have to take care of more details than just

"does the plug fit into the socket?"

If the code you have posted does not yet work you should do prelimary tests with the testcodes in robin2's nRF24-tutorial.

As soon as you show some own effort for example like this:

"I have uploaded robin2's democode from post # 2. The serial monitor shows this

........

This is how I have connected the nRF24-boards
(hand-drawn schematic)

What is still wrong that I get this error "XYZ" instead of successful datatransmission?

You should RE-edit your first post after reading how to do it here
