Believe me, if you are South Asian yourself, you have an enormous advantage in doing street photography in India because you won't stick out as a cultural outsider with a camera.
(like me, for an example)
Just practice, practice until you are proficient at the actual management of your camera - until changing iso or exposure compensation is natural and you don't need to think how.
Look at your shots to see where they fall short, where they don't show or tell what you want and then go practice more.
Digital images cost nothing.
I couldn't count the number of totally terrible images I've taken.
Eventually the technically adequate images will be in the great majority and then you can concentrate on the art of telling with a camera.
