Question: Can we have HA setup between Netgate 2100 and Netgate 4100 device?

Is it absolutely required that both devices need to be on same hardware spec with exact match?

@jasjitchopra It used to be the case to sync states, but not since 22.01, see
https://docs.netgate.com/pfsense/en/latest/highavailability/pfsync.html#pfsync-and-physical-interfaces

Edit: to clarify, the hardware doesn't have to be identical for HA, but the interfaces/interface order needed to be. If the routers have the same packages and usage then it would help if they are reasonably close in spec.
