Hey Mayank, I'm not an expert but I'm reading a lot about Google news and doing research because I also want my website https://www.geekboy.co to get index in Google news. We are going to apply after 6 months currently we are working on news quality. So I checked your website and here are my points:
1. Your authors aren't using their own image and according to journalism news should be written by humans, Google won't know if author is a human or not.
2. Some of your articles looks like reviews and Google strongly hate reviews.
Google news doesn't care about article quantity it only cares about quality.
Few days ago my website didn't have good quality news but now we're are working on quality
Work on quality! Good luck mate
