No, nebulae are not unique to the Milky Way, there are hundreds that have been identified outside it, and are generally assumed to be present in most if not all other galaxies.

No. Nebulae exist in almost every galaxy.
Nebulae can exist both within and outside of our galaxy, the Milky Way. Nebulae are vast clouds of dust, gas, and plasma in space where stars can form. They are found in many different galaxies throughout the universe.
No, nebulae do not only exist within our galaxy; they can be found in other galaxies as well. A nebula is a vast cloud of gas and dust in space, and while many well-known nebulae are located in the Milky Way, other galaxies also contain their own nebulae. These interstellar regions can form from various processes, such as star formation or the remnants of dying stars, and are observed throughout the universe.
Considering the distance to the Cats Eye Nebula is only 3,300 light years away, it is going to be within our own Milky Way Galaxy.
A Galaxy is a collection of stars. The galaxy as a whole rotates. A Nebula is a Gas Cloud. Only seen because the gas is so hot , that it is glowing.
No, a nebula is only a few light-years across while a galaxy is thousands of light-years across.
Yes, the Carina Nebula is located in the Milky Way Galaxy only 7,500 light years away from earth.
No, we believe that nebulae probably exist in every galaxy, and possibly between galaxies as well.
The Pillars of Creation or the Eagle Nebula is only about 7,000 light years from us, so it is definitely in the Milky Way Galaxy.
There is only one milky way, which is the galaxy in which we live, however there are many other galaxies such as Andromeda Nebula. :)
Probably, but impossible to tell as we are only just seeing planets within our own galaxy.
