I'd like to capture the time it takes for the server to process the request. Below is my setup:
Now the client is accessing the application reside on the server. My plan is to setup Wireshark on switch2 and switch1.
My questions are as follow: - Will the time, that I capture on switch1 when the server sends the response back, be the processing time of the server. - is it possible to merge the two captured file into one?

If you need just the 'server processing' time (please define that!), there is no need to capture on switch2 (client side).
Actually, it will be
As you can see, only 3 is the 'server (software) processing' time. But that really depends on the definition of 'server processing' time.
Furthermore: if you can neglect 1-2 and 4-5, then the time delta between client request and server response at switch1 will the the 'server processing' time.
Yes, see the tool mergecap. HOWEVER as I said, it's not necessary to capture at switch1 and at switch2 in your scenario. You can do it, but if you then merge the capture file, you will get duplicate frames, as the frames that appear at switch2 will also be seen at switch1 and vice versa.
