I tried to block incoming calls and sms in android for given numbers. after we block a number, when we getting a call from that blocked number, caller can here voice message as Number Busy.
But is there any way to change this voice message to Power off, No service, The number is not in service messages ?

The point is that the message which is returned to the other end depends on how the operator interprets your actions. When you've decided to block a call, regardless on how you do it, you have already received in, and therefore your operator knows that you are not powered off, neither off signal. There is nothing you can do on your end.

There is a nice thread discussing exactly your question:
There is a nice explanation link there why it is not possible to do so using android.intent.action.PHONE_STATE
but some nice workarounds have been suggested there, worth checking.

That is not possible as the carriers are responsible for giving those responses.
