Neutron stars
The small dense remains of a high mass star are either a neutron star or a black hole, depending on the mass of the original star. Neutron stars are formed from the core collapse of a massive star and are incredibly dense, composed mainly of neutrons. Black holes are formed when the core collapse results in a singularity with infinite density and a gravitational pull so strong that not even light can escape.
There is no "small dense object" that orbits between Mars and Jupiter. There are however numerous asteroids which are rocky objects up to a few hundred miles in diameter that orbit in this region making up what is called the asteroid belt.
A black hole is formed when the remains of a massive star collapse under their own gravity, creating a region of spacetime where gravity is so strong that not even light can escape. The mass is concentrated into a small volume called the singularity at the center of the black hole, surrounded by an event horizon beyond which nothing can escape.
They are called the terrestrial planets because they are similar to Earth (in fact one of them is Earth.
A cold dead star is called a white dwarf. It is formed when a star has exhausted its nuclear fuel and collapsed under gravity, shrinking to a small, dense, and dim object.

False. The assembly of ribosomes begins in a small dense structure called the nucleolus, not the chromatin.
It is called a forest.
Most nuclei has a small dense part. The dense region called the DNA (negative charge) and the histone proteins (positive charge).
Small agranulocytes that have a dense nucleus and very little cytoplasm are called Lymphocytes.
Every atom consists of a cloud of tiny particles called electrons that spin around a small dense core called the nucleus. The nucleus of an atom consists of protons and neutrons and is positively charged.

Overcrowding or dense population.
These small particles are known as clasts. If they are the remains of living things they may be known as bioclasts. The remains of animals are called fossils if they have hardened and become preserved.
"Small but very dense" sounds like the description of a neutron star or "collapsed matter star". Theoretically, a black hole (the only thing more dense) has no physical size at all. So, "neutron star". If the neutron star is spinning rapidly, they are called "pulsars" for the radio-wave pulses that they generate.
