Each part has a different explanation.
Stars appear to have "points" due to tiny imperfections in our eyes. Normally these get "averaged out" so that we don't notice when looking at nearby objects, but stars are so distant that they become effectively "point sources" of light, and so even small imperfections cause them to appear "star-shaped" instead of looking like very tiny circles.
Stars appear to "twinkle" also in part for the same reason, but the Earth's atmosphere has a lot to do with it. As light travels through air ... or any other material ... it gets deflected slightly, with the amount depending partly on the density of the material. Since the density of air varies depending on its temperature, as the ray of light travels through different parts of the atmosphere with different temperatures (all of which are changing and being mixed constantly by air currents), the path tends to "waver" slightly, and we perceive that as "twinkling". For the same reasons stars also appear to shift color slightly.

What is it called when there is a sun that is a satellite to another sun?
That's called a binary star. Since the mass of the two stars is fairly similar (not nearly as much mass difference as between the Sun and Earth, for example), both are in orbit; it is more accurate to say that both stars move around the common center of mass.That's called a binary star.

What do you mean when you say every pulsar is a neutron star but not every neutron star is a pulsar?
All "pulsars" are neutron stars - it's just "we" term pulsars as neutron stars who's orientation towards us shows the beam of electromagnetic radiation. Other neutron stars who's orientation, do not point towards us are not called pulsars, although they exhibit the same characteristics.
What types of stars are thought to be the remnants of supernova explosions?
Supernova explosions are believed to generally result in a black hole, as the core of the star is collapsed into an unimaginably dense point mass. One can't really say that a black hole is any kind of star. Less powerful nova explosions probably result in pulsars or neutron stars.

Does the stars mass have anything to do with the stars brightness?
the brightness of a star is dependant on its temperature and radius. however, while a star is burning hydrogen into helium (which all stars do for most of their lifespan and it's usually this kind of object we mean when we say "star") a correlation does exist between the mass of the star and its luminosity (brightness)
How do you say star in Korean?
