They all share the other two laws of Kepler...especially the "Law of equal areas" which states that objects in orbit will sweep out equal areas of the elliptic plane in equal amounts of time. The area being described as being delineated by a line frome the sun to the object in its orbit at t=0 and to the object when t=new position. The time in orbit is the time it takes the object to move from t=0 to its new position. Think of the orbit plane as the top of an oval pie. The area would look like a slice of the pie with the point of the piece being where the sun would be. The curved part of the slice would be the line of the orbit.
All elliptical orbits also have two foci with the sun being at one of them.

I can't think of anything except that the planets and quite a few asteroids are in the same orbital plane. You can't say that about comets and many don't even have elliptical orbits.

They all follow the same path on each orbit.

kepler's law i think it is that they sweep out equal areas in equal times

it's simple. the sun is at the focal point for all these paths.
