There is no such thing as a nebula star.
Rigel, Betelgeuse. Comment: They are two of my favourite stars, but they aren't in the Solar System. There's only the Sun that's a star in our Solar System.
Two forces that act on particles inside a nebula are gravity, which pulls particles together to form new stars and solar systems, and radiation pressure, which pushes particles apart due to the energy emitted by hot stars within the nebula. These forces must be balanced for a nebula to maintain its structure and not collapse or dissipate.
Roughly 98% of the solar nebula's mass consisted of hydrogen and helium gases. These two elements are the most abundant in the universe and are the primary components of stars like our sun.
A solar system consists of one or two stars and one or more planets. A galaxy consists of numerous stars/solar systems.
Most solar systems have one star, like ours does. Some have two stars, known as a binary system.

Two stars orbiting one another are in a Binary System
No. Only the one. We call it the Sun.
Hydrogen and helium were the two primary gases present during the formation of our solar system. These gases dominated the early solar nebula from which the Sun and the planets eventually condensed.
Two types of stars that can form from a nebula are main sequence stars, like our sun, and giant stars, which are larger and more luminous than main sequence stars.
To be a solar system requires only one sun and things orbiting it. Most stars are by themselves, with things orbiting them. There are some binary systems, where two stars are together, but they are not as common and our solar sun is not part of a binary system.
A Nebula is A Cloud in space of Steller Dust And Gas In Which dust and gas particles collapse inwards to form new stars and the remaining debris could form new planets. Picture It Like a bag of soil. The Nebula Cloud is the soil and new stars are growing from it. Sometimes when large masses of matter collapse inwards new galaxies are formed.
