1. It's completely safe to provide Zebpay with your PAN card because they are secure and trustworthy exchangers in terms of Bitcoins in India.
2. Coinsecure asks you for documents like Passport, Driving License, PAN card, etc. of which you can provide them any.

Is it safe to provide IFSC code to anyone? (Like we are not suppose to share Debit card details, pin no. Etc)
First of all welcome to crypto community ,zebpay and coinsecure are safe and quite fast in transaction.there are thread called 'help' and "introduction" ,you can visit there for your query.
Thank you. Can you provide link for those thread?
IFSC code is used to send funds to your bank account. And every Bank's branch has different and unique IFSC code. As far as I know it is safe to give your IFSC code. I suggest to keep a separate account without much cash in it to do online payments and other card payments. In this way you don't have to fear anything. Keep like 5000 rupees in that account and if you need money to spend urgently, only then transfer the money. Try to have another account which does not have debit card or anything linked to it. Keep your savings in this account.
