Is it possible that Bode plot can have multiple transfer functions in S domain or there is always one to one mapping between perticular bode plot and transfer function... Actually I have to design filter and I have its bode plot. I have derived corresponding transfer function .But it is of order 5 and I want to have transfer function with lower order. So is it possible to have lower order filter with same bode plot response

Leaving aside the theoretical part of the question, you can use command tfest from System Identification Toolbox to identify a transfer function of specified order from frequency domain data.
