It is not known. Scientists are still not sure how many dwarf planets are in the solar system or how many true planets are in the galaxy. If estimates from our solar system apply elsewhere, however, the number is probably in the trillions.
No. There are dwarf planets in our own solar system that are smaller than Pluto and there are many undiscovered planets in the Milky Way that would be smaller than it, but are too far away to see.
No one knows. Astronomers are scanning the visible stars of our own Milky Way galaxy for planets orbiting faraway stars, but such planets would have to be nearly the size of Jupiter to be detected at such distances
There are millions, possibly billions, of planets in the Milky Way. An exact number will never be known.
The planets were formed in the Milky Way. Our Galaxy (Milky Way) is older than the planets of our solar system.

There are more than 350 known planets in the milky way, with only 8 in our solar system.
Most planets that have been discovered are in the Milky Way
Pluto is a dwarf planet located in our own Milky Way galaxy. It orbits the Sun in our solar system, along with the other planets.
The entire solar system is in the milky way, with all the stars you can see.
It isn't even clear how many dwarf planets our own Solar System has (it may be some tens of them, hundreds, or even thousands) - much less how many there are in the entire Milky Way or in other galaxies.
The Milky Way has somewhere between 100 and 400 billion stars; most of those are red dwarf stars.
