"Stellar masses" is not a unit of mass - perhaps you mean "solar masses". Depending on the remaining mass - after the supernova explosion - either a neutron star or a black hole. In the case of four stellar masses, probably a neutron star; it would require a more massive star than that to become a black hole.
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.
The small dense remains of a high-mass star are called neutron stars or black holes, depending on the mass of the star. Neutron stars are formed when the core collapses under its own gravity, while black holes are formed when the core collapses into a singularity.
A dwarf star is denser than a giant star. Dwarf stars have a higher density due to their smaller size and higher mass compared to giant stars. Giant stars have larger volumes and lower densities as they have expanded and become less dense towards the end of their life cycle.
This describes a white dwarf, which is a small, dense star that remains after a star has exhausted its nuclear fuel and shed its outer layers. White dwarfs emit heat and light as they slowly cool down over billions of years.
After the Red Dwarf phase, the life of the star ends. It begins to shed its outer layers into a cloud, called a planetary nebula, until only about 20% of the star's mass remains. The star will then continue to cool and shrink until it becomes a White Dwarf.

A giant star is a giant dense ball of gas that is near its last stages of a star.

one is big one is small
Once a medium sized star has consumed all it's fuel it becomes a White Dwarf star (just the extremely dense core of the original star remains composed mainly of carbon). A White Dwarf star will, however, eventually lose it's heat to become a Black Dwarf.

Most stars (including our own sun) as they grow older, eventually cool, expanding into a red-giant. After a period of time as a red-giant, they shrink to a hugely dense but very small white dwarf.
I suppose so if you were a really giant giant or you just had a small model of one.
I suggest you do some reading on both, to get an idea what a neutron star really is, and what a supergiant is. For a start, some differences are: their diameter; their density; the fact that a neutron star no longer produces any energy.
