Can I renew my Indian passport if it expired in 2017, if not will my?
There is no such thing as renewing of an Indian passport. Getting a new passport after expiry is called re-issue. Every reissued passport has a new passport number. You cannot have the same passport number on a new passport. That is not possible. It is regardless of when your old passport expired. New passport always has a new number and the old passport number is also mentioned.
