I have tried all the options given to make old 2014 iMac 2014 to use as display monitor for new iMac 2021 iMac. Seems like I have wasted my money on new iMac and wires such as thunderbolt 3 to thunderbolt adapter and thunderbolt cable nothing works.
any idea why its not working?

No. A 2021 iMac is later than 2019, not earlier.

Yes…
"The other Mac that you're connecting it to must have been introduced in 2019 or earlier and have macOS Catalina or earlier installed."
Use your iMac as a display with target display mode - Apple Support

You may be able to connect your VGA monitor using this adapter…
