How to install/swap Recovery on Redmi 1S, running on CM11

I had install TWRP on Redmi 1S (while running on stock MIUI ROM) and I installed CM11 ROM. It is running fine.

My question is

1) How do I upgrade the TWRP with latest version?

2) How to I change the TWRP to CWM (or vice-versa)?

3) Does CyanogenMod has its own Recovery? If yes, how to get that on my device?
