Glowing gas clouds that will eventually become stars--as the question is phrased the answer must be: Reflection Nebulae. These are clouds of gas lit by nearby stars. Eventually this gas will be incorporated in new stars, but probably not for a long, long time.
The asker may have been after: What are the interstellar gas clouds glowing in THE INFRARED that will eventually become stars?
The answer to this is a proto-stellar cloud.
Previous answer:
Protostars
This is not correct. A protostar is exactly what it sounds like--a star in the process of forming. In the protostar state, a gaseous mass has formed a central clump surrounded by a thick disk of gas and dust.
The cloud of gas and dust surrounding a protostar make it very hard to detect, and in fact they are only seen in the deep infrared--they are not visible to the human eye.
Nebulae (plural of Nebula) large clouds of gas and dust, created by the demise of other stars. These nebulae act as galactic "nurseries" for the creation of new stars and planets.
Molecular clouds
it can alter the way we see the stars. It impeds our attempts to look at space. The dust, moisture, pollution and clouds get in the way of a clear veiw.
White dwarf stars are theorized to be the final evolutionary state of all stars that did not become neutron stars. This stage is the longest in a stars life outside of black dwarfs which are white dwarfs that have cooled dramatically.
All matter is composed of either a single element or a number of elements, minerals, people, stars, fish and clouds included.
Glowing cloud sections that will eventually become stars are protostars. These protostars are clouds of interstellar gas and dust, which gradually collapse causing a hot dense core to form and evolve into a star.
Clouds of gas will collapse, under certain circumstances, due to their own gravity. These will eventually become stars. This process is described in more detail in the Wikipedia article on "Protostars".
The glowing clouds that you see in pictures from space are called emission nebulas. A emission nebula is a cloud of hot, glowing cloud of gas and dust in space. These nebulas absorb the light of nearby stars and reach very high temperatures. The high temperature causes them to glow. Emission nebulas are often found in regions of space where new stars are forming.
protostars That is called a Nebula. It is a giant cloud of gas, made up of various elements including hydrogen, helium and others. The clouds float in space and contain everything necessary to form a star and a solar system. Eventually something causes the gravity in the nebula to become unstable. For instance, shock waves from a super nova or something similar. These shock waves cause the cloud to start to move, which if strong enough, will cause the cloud to start spinning. Gravity takes over and eventually you have a star. This is a gross oversimplification. Much more happens than this. But it answer the question fairly quickly.

White Dwarf
Stars
Stars do not have clouds.
No, a nebula is a place where stars are born. Stars and clouds are very different.
Yes, Lionblaze and Cinderheart become mates in the Omen of the Stars series. Their relationship develops throughout the books, and they eventually become a couple.
Stars form from collapsing clouds of dust and gas within regions of molecular clouds, often called stellar nurseries. As the cloud collapses its density and temperature increase until it eventually reaches the point where a start begins to form in the center of the cloud.
Low and medium sized stars will end up as white dwarfs.
