We have brocade ED-DCX-4S-B as core switches and are running at firmware version v7.1.1.c1. Recently we have received new set of M5424s (attached to Del Chassis) running at Firmware version v7.4.0b. In this context, I would like to know how could best fit the firmware versions when the new switches join the domain. Currently we don't have any plan to upgrade the core switches. Your feedback is much appreciated.

Yes and no.
in example some old 4GB Platforms supported only FOS 6.2.2 but can operated as well with FOS 7.4.x
brocade 300, 5100 and 5300 can interoperate with FOS 6.1.0e or higher
I would suggest, for details to refer FOS 7.4 Release Notes.
