If you are asking if one hour is enough to get to the second flight then it is a very tight window because you will have to do the security check-in again and then reach the Gate in that huge terminal but if your first flight reaches on time then it is doable and second flight officials will also be there to connect with you and help you but it will be a race.
If the arriving and next flight both are on Vistara, then it is a little easier because Vistara flight normally waits for a few extra minutes if passengers are coming from their connecting flight.
