I m 24 and I want to learn singing . Is it possible to start at this age from the beginning. Is Anyone can teach me vocal training making me feel comfortable at the same time and encourage me. I just want to follow my passion. 

Hi Chetan! I echo the reaponser you've already recieved. There's no age for learning. You start where you are with the tools you have. It's like going to the gym. You learn to progress not because you already know things. So keep your apprehensions and dive right in! Wishing you the best for your musical journey! Don't forget to have fun along the way :) 

It's never too late brother, but you need to put some real work in it. And it is good to start with a reference instrument so that you can have a idea of those abstract concepts about music in a more conceivable way. At early age we have some favors of mother nature that we can learn those amazing concepts in a more intuitive way while growing up but at adult age these things are rather hard to put through. So just practice with a instrument and gather some information and then go for lessons.
