There are none.. Either you can make it on your own using TWRP Builder or Build it directly how TWRP is build and then post it here after testing!

Even if I have working twrp image how can I boot to recovery from fastboot mode?
After flashing I can only boot to normal mode and stock rom will replace twrp with stock recovery.

I don't have the device but adb reboot recovery should work right? Or Power Don + Power should lead to recovery in most mobile phones.
You can even use "fastboot boot recovery.img" where recovery.img is your TWRP recovery. you can use it to boot into TWRP and decrypt device if needed and then flash it permanently!

I am using Ubuntu as PC OS.
I unlocked bootloader of realme c2 by following the steps which I described on page 1.

Are you following the procedure exactly?
I think you have driver issue.

check USB devices in Device Manager when Phone is connected in fastboot mode.
Check by connecting USB cable in USB 2.0 port.
