See for INR we just have some handful of exchanged which offer some good services along with great customer support. But which exchange you can choose would certainly depend upon your requirement. I can review two or three for you.

Zebpay: zebpay is not actually an exchange merely a wallet or a platform where one could buy bitcoins. The bid ask orders on wallet do not really get accepted so quickly because they don't show list of active orders up there. Generally you have to buy/sell bitcoins using the inbuilt option in which you are bound to buy it at price which zebpay wants. Zebpay is best if you continuously send your bitcoins as the transaction fees are too low as they do processing in batches. Moreover it does not supports any other coin.

Koinex: It is the first live trading exchange of India. They are even listed on coinmarketcap as the only exchange trading in INR but they are at their budding stages as well. Their customer support isnt upto the mark yet they support a lot of major coins so you can even trade on the platfrom.
