It depends exactly what you mean. You probably mean the Red Dwarf stars. I only know of one element that they make and that's Helium.

Is the color at the star related to its size?
Generally, yes. For stars on the main sequence, meaning that they fuse hydrogen at their cores, mass, size, color, brightness, and temperature are all closely related. More massive stars are larger, brighter and hotter than less massive ones. The least massive stars are red. As you go to more massive stars color changes to orange, then yellow, then white, and finally to blue for the most massive stars.
Which of these elements does this star contain?
Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).Of which elements? - Stars usually consist mainly of hydrogen, less helium, and small amounts of the so-called "metals" (which, in astronomy, means any heavier elements).
What is the relationship with mass and the end stages of stars?
As stars burn, they shed matter, becoming less massive slowly throughout their life cycle. This reduction in mass necessarily lessens their gravity, causing the stars' diameter to increase. So, many end-stage stars will be huge and bloated. Massive red giant stars are examples of this.
What happens when a stars core runs out of oxygen?
Unless a star ts very old and very massive, it will not consume oxygen. Stars are powered by nuclear fusion, which fuses hydrogen into helium. When a star runs out of hydrogen at its core it expands into a red giant and starts fusing hydrogen in a shell around the core. If the star is not massive enough to fuse helium, then it will shed its outer layers and leave a helium while dwarf where the core was. If it is massive enough, it will fuse helium into heavier elements up to oxygen. Most stars to not make it past this stage. More massive stars, though fuse elements such as carbon and oxygen into neon, magnesium, and sulfur. If at any stage the star can fuse no more, the it sheds its outer layers and leaves behind a white dwarf. The exception is if the star makes it as far as fusing iron. If that happens the core will stop producing energy. The core will collapse into either a black hole or a neutron star and the rest of the star's mass will be blown away in a massive explosion called a supernova.
Are all-stars the same as the sun?
No, some are hotter/cooler, some are more/less massive, but they all follow the same life processes.
What force causes extremely high mass stars to turn into black holes instead of nuetron stars?
Black holes are formed by super massive stars when they collapse. Less massive stars will form neutron stars. Therefore, the original size and mass of the star will determine if a black hole will be created when the star collapses.
Are all-stars made of similar elements?
Younger stars often are made up mainly of hydrogen, perhaps with some helium. Less massive stars will only fues hydrogen into helium, so eventually they will end up having a lot of helium. More massive stars however will eventually start fusing helium to metals, i.e., heavier elements. In any case, the "metallicity" (percentage of elements heavier than helium) and the percentages of different elements should vary somewhat between different stars.Younger stars often are made up mainly of hydrogen, perhaps with some helium.

What is the combining of less massive elements on a star?
Nuclear fusion.
In Binary Stars the initially less massive Star can die first?
Yes they can

How does a stars mass affect its life cycle?
The more massive a star is, the less its life time.
Can a star less massive then the sun become a supernova?
Any stars less massive than our sun do not explode in a supernova. They will slowly cool down and burn out forming an "ember" (a.k.a. white dwarf).
Why do less massive stars age less slowly than big stars?
The pressure and temperature in the core of a star varies, depending on the star's mass. And the energy production is highly dependent on the temperature.
Why are the oldest stars called the red stars?
The Milky Way similar to the graph of the sombrero galaxy NGC4594 - a disc shape of spiral galaxy, contains about 200 billion stars. In the galactic plane above and below a halo, including billions of years ago the ancient star formation. Generally, these ancient star contains less gold, platinum and heavy elements such as uranium, but new research shows that the universe was formed at the early stage, giant exploding spray into the space of the heavy elements formed the enriched new stars.
Element abundantly present in the universe especially in stars?
The two main elements in stars are Hydrogen and Helium. Stars start out as mostly Hydrogen and produce Helium. There are less amounts of heavier elements like Oxygen, Neon and Iron in stars
Why is massive star more luminious than a less massive star?
This fact can explain with the help of nuclear fusion in small stars and massive stars in small stars like our sun nuclear fusion followed by the proton -proton chain reaction in which main products are positron, gamma ray photon, neutrino and isotopes of hydrogen and helium and energy released in millions of electron volts but in the case of massive stars nuclear fusion is followed by the carbon-nitrogen-oxygen cycle and helium can further transform into the carbon by triple alpha process and in the massive star much heavier elements can burn producing very large amount of energy than our sun and some of the massive star can produce luminosity 60000 times more than our sun
