Yes, they are in order. Usually. I believe that Uranus and Pluto occasionally switch orbits, but I wouldn't bet my last nickel on that.

I'm sure some astronomy whiz here on FR will be able to tell you for sure.

That's Neptune & Pluto... in fact, Pluto only within the last few years crossed back and once again became the more distant planet.

Pluto has a somewhat large eccentricity (compared to our Earth) and during its perihelion (closest point to the Sun), it is indeed inside the orbit of Neptune.
