Hello,
I want to design 5th order butterworth filter.
.............
Which steps can I track?
How deep is your knowledge?
Do you know the difference between several available design strategies active, passive, cascade design, direct design,...)?
By the way - there is no bandpass of fifth order. The order is determined by the number pole pairs [correction: number of poles] (n=2,4,6..) - and it is not a simple task to design a Butterworth bandpass of order n=4 or n=6.
Are you allowed to use a filter design program? This would be the best and easiest way for designing such a filter.
Passive or active?
Impedance? Voltage?
Linear or Switched Capacitor blocks or Digital with filter libraries?

I don't have knowlodge much. I can use pspice .
If This filter will be designed, Can I connect in series 2th low pass and 3th high pass?
So - what do you really need?
I think we can assume BPF=LPF and HPF which are implemented by cascade
The order can also be implmented in odd numbers using switch cap block filter chips.
I think the easiest solution uses LTI's 5th order B LPF filter on a chip with adaptation using external RC for HPF, combined using 2 chips and a clock.
