planetesimals formed the disk
The solar system did not form from a nebula at all. Our solar system formed from a rotating cloud of gas and dust, our sun formed at the center and planets formed from the surrounding matter. when our sun became large enough to support nuclear fusion, the solar wind created blew away most of the gases present. A planetary nebula is formed after a star runs out of fuel (Helium) and collapses inward on itself due to the massive amount of gravity and the now unstable balance of the star. the pressure then becomes so great that the gases that had been pulled inward explode outward at an incredible speed. The Cats Eye Nebula is a good exampleFile:NGC7293_(2004).jpg
the solar nebula was 98% hydrogen and helium gas

Scientists believe that the Solar System evolved from a giant cloud of dust and gas. They believe that this dust and gas began to collapse under the weight of its own gravity. As it did so, the matter contained within this could begin moving in a giant circle, much like the water in a drain moves around the center of the drain in a circle. At the center of this spinning cloud, a small star began to form. This star grew larger and larger as it collected more and more of the dust and gas that collapsed into it. Further away from the center of this mass where the star was forming, there were smaller clumps of dust and gas that were also collapsing. The star in the center eventually ignited forming our Sun, while the smaller clumps became the planets, minor planets, moons, comets, and asteroids.
Uranus was formed from the light gases of the outer solar nebula.
No. A nebula is generally much larger than a solar system. We believe that our sun and solar system came to be when a nebula collapsed under the influence of gravity, and the gas of the nebula became the Sun and our planets - and everything else.

A solar nebula is related to the formation of our Solar System, any other nebula is just a nebula.
Well, there was the Big Bang, and then the Solar Nebula collapsed ... you might want to be more specific.

All of the solar system originated from a nebula that collapsed under the influence of gravity. So yes.
