No, dark matter is quite a different kind of thing. A dark hole may have absorbed some dark matter, but pressumably that would become indistinguishable from the normal matter, once it gets crushed by the enormous gravity of the black hole.
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.

I think that's unlikely. The only relevant features of black holes are its mass, electric charge, and rotational momentum. What makes dark matter different to baryonic ("normal") matter is that it doesn't interact with normal matter, except through gravity - so it seems that none of the differences would be relevant, once such matter is converted to a black hole.
Dark matter is a mysterious substance that makes up a large portion of the universe's mass, but its exact nature is still unknown. While some theories suggest that dark matter could potentially be made up of black holes, this idea is not widely accepted among scientists. More research and evidence are needed to determine the true nature of dark matter.
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.
Dark matter, dark energy, nebulae, stars, black holes, planets, comets, asteroids, meteors, satellites, supernovas etc. make up an elliptical galaxy.
A broader answer would still be no. There is no consensus on what the so-called "dark matter" is.
Black holes are made up of a super dense core called a singularity, surrounded by an event horizon. The singularity is thought to contain all the mass of the black hole, but it is not made of matter as we know it. Instead, it is a point of infinite density where the laws of physics break down.
Black holes are not composed of matter, and do not have a chemical formula.
Black holes are hidden behind an even horizon we do not know what happen in side them.
If by "heaven" you mean outer space, it is made up of the same 90 elements or so that are found on Earth. However, in outer space there is also matter that is not made up of atoms - including black holes, dark matter, and dark energy.If by "heaven" you mean a metaphysical heaven, as in what expects us in the afterlife - well, nobody really knows.
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.
