How  can I decide the cut-off frequency (low and high) in band pass filter?

What function are you trying to use?  Doing a quick search for a bandpass filter and the functions have the cut-off frequencies as inputs.  So I am not sure what you are trying to get at.

That's a pretty ambiguous question.  That's like saying, "How fast should I drive?"  The answer to both questions is, "It depends."

A picture without words to explain what it is you are trying to show us doesn't help.

I accidently sent it sorry. My problem is with the cut-off frequencys. I am trying to set it lower than the 500 because my fs is 1000 and with that lower frequency should be lower than 500 and maybe it can be 450 and higher can be 485 right? 

Note: I am trying to filtering noise from the sinusoidal source.

Thank you for all of your answers.

You really need to take a course in Signal Theory, and learn about digital and analog signals.
