I would like to check if my cisco 2960-24TTL switch can install firmware version 15.2(4)E6 or 15.2(6)E1?
Not supported.
The "highest" version the plain/legacy 2960 can go is 15.0(2)SE train which 15.0(2)SE11 is the last-and-final version.

Will there be any issue if i use firmware version from other Cisco 2960 models like 2960x etc to install onto Cisco 2960-24TTL?
Yes, if forced to load an IOS which is not supported, the switch will go to ROMmon.
