In my scenario, I have three systems A, B and C. I am creating load on System A and system A communicate in following way A -> B -> C. At last response comes to system A in following way A <- B <- C. I am being able to capture TPS via Jmeter for system A only. How can I capture TPS for the other two systems?

JMeter knows nothing about the architecture of your application, it treats the system under test as the black box
If you want to check systems B and C performance you need to mimic the communication between A and B and vice versa in the JMeter test, the same for B and C. The approach is known as Isolation Testing
In case if for some reason it's not doable you can try to collect the information from the systems B and C using i.e. JMeter PerfMon Plugin which supports a variety of metrics and allows executing arbitrary commands/reading files in order to retrieve and plot the collected information.
