From it's discovery in 1930 until 2006, Pluto was the ninth planet. In 2006 it was reclassified as a 'dwarf planet','so is no longer a 'planet'. There are only eight bodies in our solar system now internationally recognised as planets.
No
No, Pluto was the ninth planet, but now, there is no ninth planet in this Solar System, since Pluto got turned into a dwarf planet. Your anus is a planet.

The ninth planet of our solar system was Pluto. However - the planet was downgraded from planet status, and is now considered part of the Kepler belt.
There are now only eight planets in the solar system. In 2006, in a controversial decision, Pluto was demoted to the status of a "dwarf planet."
Back when Pluto was a planet and not a dwarf planet, it sometimes Neptune to be the ninth planet because their orbit crossed. Now that Pluto is a dwarf planet, there are only eight planets in the solar system.
"The ninth plant" is meaningless, since there's no natural ordering for plants."The ninth planet" is also meaningless, because there are only eight solar planets, and there's no natural ordering for planets in general. "The ninth planet around the star Mumbojumbo" might have some meaning, assuming that a) there were a star named Mumbojumbo and b) it had at least nine planets, but as it is, your question cannot be answered.

Pluto
Pluto has been recategorised as a dwarf planet. Until its change in status it was considered to be the ninth planet from the sun. Though, on occasion, its orbit brought it closer than to the sun than Neptune, the eighth planet.
Yes, Neptune is the eighth planet, and the farthest from the Sun. Back when Pluto was considered a planet, Neptune became the ninth planet for 20 years of Pluto's orbit as Pluto is closer to the Sun than Neptune for part of its orbit.
No. The fifth planet is Jupiter. Pluto was once considered the ninth planet, but is no longer considered a planet.
