Currently I am using M-Audio fast track pro and I am thinking new keyboard which does not has MIDI in/out, but this has USB MIDI connection.
If I use both connection for Sonar X1, does this work? Thank you for your advice.

If you are talking about having 2 separate keyboards send MIDI data to Sonar, that works fine - you just have to make sure input devices are checked in preferences, and for your USB-connected keyboard make sure you have appropriate drivers for the keyboard installed and loaded.

If you were referring to something else, please clarify,

Another FYI, you may have a soft synth or two that will need to be "told" which input is meant for it, typically a setting in the synth itself.
