The question does not make sense. Please restate the question, giving more details, so we can understand it and answer it.
It may be either. Juvenile means young.
Technically a dead star is when a star no longer undergoes nuclear fusion. Depending on the mass of the original star this will either be a white dwarf, neutron star or black hole. These are called stellar remnants.
Yes.
black hole
A star with half the mass of the Sun will shine dimly for a VERY long time. The more massive the star, the brighter it is and the more rapidly it develops and evolves.

Since it has about twice the mass of the Sun, you can expect it to be relatively young. Such massive stars burn out fairly quickly (for a star).
If a star has more mass, there will be more gravitational attraction. The star's material will get closer together, and the star will have more temperature and more pressure.

No. A white dwarf is a remnant of a dead star.
No, it's a hypergiant. A dead star is a collapsed star - not a giant in size (the mass may be considerable, though).
Yes.
The more mass a star has the less time it has to live or "be a star." The less mass a star has the longer it has to live.
A star has more mass than a planet.
neutron star is a stellar remnant so it is neither a young star nor an old star . It is formed by the gravitational collapse of massive star and are composed of neutrons . neutron star has a mass in between 1.35 to 2 solar masses

The mass of a star affects the lifespan of the star. The less the mass, the longer life span of the star. More massive stars burn up their fuel more quickly than the smaller stars. As the massive stars begin to burn the fuel and become smaller, the life span increases.
