The largest and oldest stars are called Red Giants, although, some very small and incredibly massive stars, called Neutron stars, do exist. One tea spoon of Neutron star mater would weigh over 50 tonnes!
High mass.
What are the small dense remains of a high mass star
The sun is an intermediate-mass star.
the high mass star's core collapse because its gravity
No, it's low mass.
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.

the high mass star's core collapse because its gravity
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.
The Sun is a medium mass star in main sequence.
A protostar is the first building block of the main star. As it has not yet accumulated enough mass to join the main sequence, it will be smaller than the main star. The next stage will be a T Tauri star.
no the sun is a medium mass star.
