delta is flying about 5 times daily from jfk to atlanta. so why does the 1st flight take about 10 min. longer.
.....than the 3rd one, and the 2nd 15 min. longer than the fourth one? even thought they should fly the same route and all non-stop?!

It depends on the routing and amount of air traffic at that particular time of day.
2 :
They factor in possible delays and the amount of traffic at both airports and in route. Also, the plane may fly slower than the other 4 planes used on that route.
3 :
I'll bet the pre-flight check is longer for a plane to start. The rest of the planes are ones coming in, refueling, and taking off again.
4 :
Maybe the cooler temperatures in the morning decrease the true airspeed because the air is more dense. But most likely its the amount of traffic at the given times.
5 :
Its called a "block time" and it builds in potential delays due to congestion at JFK and at ATL. Both those airports are subject to a phenomenon known as departure banking, where everyone tries to leave at the same time (maybe...8am) and the result is the airport equivalent of gridlock. those times are based on historical averages saying that you will probably be delayed significantly if you try to book on one of the prime-time flights. It basically allows Delta to absorb delays without reporting the flight as late, because they have already told both you and the FAA how long it is probably going to take to get there.

It may have to do with any number of issues: Expected morning back-ups as everyone tries to leave at the same time. Type of aircraft in use for that flight, some carriers will use different types (larger or smaller) on the same route through-out the day. Expected wind patterns through-out the day.
