Dark matter is by definition not visible nor reactive to the electromagnetic force; this would exclude visible matter, including stars. One might argue that the effects which dark matter has been used to explain could be consequential to gravitational pull from ordinary stars, perhaps owing to a gross miscalculation or an incomplete understanding of gravitational force -- but this would be a different position than to say dark matter itself is stellar material.
The universe is primarily made up of dark matter, dark energy, and normal matter. Normal matter includes atoms and particles like protons, neutrons, and electrons that make up stars, planets, and the things we see around us. Dark matter and dark energy are mysterious components that scientists are still trying to understand.

This is not known. All that is known about dark matter is that it has mass. Searches are underway to try to work out what it is. The existence of dark matter was learned rather recently, and its composition is still being speculated, hence the name. There are several theories about what dark matter may be made of.
Galaxies are mainly made up of stars, gas, and dust. Stars are the primary components, with gas (mostly hydrogen and helium) and dust filling the space between the stars. Dark matter is also thought to make up a significant portion of a galaxy's mass, even though it cannot be seen.
An atom is a nucleus surrounded by several electrons. The nucleus is made of protons and neutrons; these can be further subdivided into quarks. As for dark matter, no one knows what it is. The only evidence for dark matter is the fact that the "light matter" (the stuff we can see in space) isn't nearly enough to create enough gravity to hold the universe together. It could be anything that has mass and isn't directly observable - white dwarves, black holes, bits of rock, as-yet-undiscovered kinds of fundamental particle, ... It could be a bit of each. Given that space is only illuminated in small patches where the stars are, it's not at all surprising that there appear to be things we can't see. In fact, dark matter is so elusive that in recent years some astronomers have begun to doubt whether it even exists, saying that maybe the general theory of relativity needs to be modified to add more gravity over larger distances. So dark matter could be made of atoms, like light matter - it could be something quite mundane. Could atoms be made of dark matter? In other words, could dark matter consist of subatomic particles? If it did, then it would be made of atoms (because nothing else is stable and made of subatomic particles).
Black holes are not made up of dark matter. Dark matter is a mysterious substance that makes up a large portion of the universe's mass, but black holes are formed from the collapse of massive stars.
Dark matter is a mysterious substance that does not interact with regular matter, so it is unlikely you would be able to walk through a wall made of dark matter. Our current understanding of dark matter is that it exists in a halo around galaxies and does not clump together like regular matter to form solid structures like walls.
Dark matter in galaxies cannot be made of neutrinos because neutrinos are too light and move too quickly to account for the gravitational effects observed in galaxies. Neutrinos also interact weakly with other particles, making them unlikely candidates for the majority of dark matter in the universe.

A broader answer would still be no. There is no consensus on what the so-called "dark matter" is.
Stars, dust, gas, black holes, dark matter...By far the most significant component, in terms of mass, is dark matter, making up about 80-90% of a galaxy's mass.
Galaxies are made up of billions of stars, along with gas, dust, and dark matter. These components come together to form vast systems that are bound together by gravity.
The Milky Way has a lot of stars, but not only that. There is also dust, gas, black holes... and an estimated 80% of the Milky Way's mass is made up of dark matter, meaning that nobody knows what it is really made of.

"A binary star is a stellar system consisting of two stars orbiting around their center of mass for each star, the other is its companion star. recent research suggests that a large percentage of stars are part of the systems with at least two stars. Binary star systems are very important in astrophysics, because observing their mutual orbits allows their mass to be determined. the masses of many single stars can then be determined by extrapolations made from the observation of binaries."
Dark matter, dark energy, nebulae, stars, black holes, planets, comets, asteroids, meteors, satellites, supernovas etc. make up an elliptical galaxy.
