The sun is neither a supernova nor a white dwarf. The sun is a main sequence star. A supernova is not a kind of star: it is the explosion of a massive star.
Our Sun is currently a main sequence star. It is not a supernova, as supernovae are massive explosions that occur at the end of a star's life cycle, and it is not a white dwarf, which is a type of star that has exhausted its nuclear fuel and collapsed to a very dense state.
Our sun does not have enough mass to undergo a supernova event. The sun is classified as a small to medium-sized star, and it will eventually evolve into a red giant and then a white dwarf over billions of years, but it is not massive enough to explode in a supernova.
A Chandrasekhar mass is the maximum mass limit (about 1.4 times the mass of the Sun) that a white dwarf star can have before it collapses under its own gravity and triggers a supernova explosion. When a white dwarf accretes matter from a companion star or merges with another white dwarf, exceeding the Chandrasekhar mass, it can collapse and explode as a Type Ia supernova.
No. When the sun dies it will expel its outer layers in a series of gradual pulses and leave behind a white dwarf.
A white dwarf supernova occurs when a white dwarf in a binary system accretes matter from its companion star, surpassing its Chandrasekhar limit. This type of supernova is not usually associated with a specific type of star, but with the evolutionary path of the white dwarf in a binary system.
A white dwarf supernova occurs when a white dwarf star in a binary system accretes material from a companion star, causing it to exceed the Chandrasekhar limit (1.4 solar masses). The core then undergoes a runaway nuclear fusion reaction, leading to a catastrophic explosion that destroys the white dwarf.

No, stars less massive than the Sun do not have enough mass to undergo a supernova explosion. Instead, they may end their lives as a white dwarf or, if they are even less massive, a planetary nebula. Supernovae are events associated with more massive stars.

White Dwarf.
The white dwarf collapses under its own gravity. This starts very rapid nuclear fusion reactions. It explodes as a supernova and "stuff" is scattered into space. Essentially nothing of the white dwarf, as an object, remains.
A black dwarf is a dead white dwarf. By dead, I mean a star that no longer burns. A white dwarf, in turn, is a dead "moderate" star (a star like our sun). So a black dwarf is a star that's died twice, with mass not much higher or probably lower than that of our sun. A supernova, is the "death" of a star that's really huge. By huge, I mean it has a mass that's considerably higher than that of our sun. That kind of star doesn't turn into a white dwarf. Rather, it becomes either a neutron star (pulsar or non-pulsar) or a black hole.
No. It's a white dwarf, meaning that it has no more fuel left for such things.
A giant star would experience a supernova explosion, in order to become a white dwarf.
