The question does not make sense. Please restate the question, giving more details, so we can understand it and answer it.
Juvenile star is typically classified as a low mass star, as it is in the early stage of its life cycle. These stars have a mass similar to that of the Sun or less. They are characterized by their long lifespan and relatively stable nature.
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.
A dead star would basically be one that ran out of fuel. Such a star no longer has the radiation pressure to keep it "blown up"; it will collapse. Depending on its mass, it will collapse into a white dwarf, a neutron star, or a black hole.
A star with half the mass of the sun would live longer as it burns its fuel at a slower rate due to lower internal pressure and temperature. The more massive star would burn through its fuel more quickly and have a shorter lifespan.
Main sequence stars best obey the mass-luminosity relation. This empirical relation states that there is a direct relationship between a star's mass and its luminosity. In general, the more massive a main sequence star is, the more luminous it will be.
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).
A small dead star is typically a white dwarf, which is the leftover core of a star that was not massive enough to become a supernova. White dwarfs are very dense, about the size of Earth but with the mass of a star.
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.
Generally the larger the mass of the star, the more luminous it is.
No, unless it somehow acquires more mass. It requires more mass to become a neutron star.
