Hi @gulvir,
Luckily, there is a handy step by step guide on How to replace a tap washer, that will walk you through all the steps.
Have a read and let me know if there is anything you are not quite sure of. I can assist further if required.

I just want to know ,how to remove these tap handles. Which tool i will use. Otherwise i know how to change the washer.
Thanks,
The C and H buttons on the front of the tap are a cover. You can see there is a hex head around them in the chrome. To remove the cover, I am assuming based on this fact that you need to rotate them counterclockwise, using this chrome hex head to grip them, to remove the caps.
You should be able to use a tap spanner or adjustable spanner to do this. Once those covers are off, you should be able to simply pull the tap handle off.
Let me know if you have any further questions.
