The color of a star is mainly related to the star's surface temperature. This is only remotely related to the star's mass; for example, high-mass stars can either be very hot (blue) or not-so-hot (red), depending on the phase in the star's life.
High mass.

The sun is an intermediate-mass star.

Depends on the mass. Stars can come in many different colors, and no color at all -> if the mass is high enough, the star is considered a black hole, where the mass generates so much gravitational force that nothing, not even light, can escape.
High mass.
A high mass star will leave behind either a neutron star of a black hole.
High mass.
no the sun is a medium mass star.

It can't. A blue star is a high-mass star. A yellow star has a medium mass.
It may be either. Juvenile means young.
