When a super-giant star explodes it shines brighter and turns into a supernova.
Iron is the heaviest element formed by fusion in the core of a supergiant star prior to its supernova explosion. Elements heavier than iron are typically formed during the supernova explosion itself through nucleosynthesis processes.
Nebula. Some nebulae are formed as the result of supernova explosions. The material thrown off from the supernova explosion is ionized by the supernova remnant. One of the best examples of this is the Crab Nebula, in Taurus. It is the result of a recorded supernova, SN 1054, in the year 1054 and at the centre of the nebula is a neutron star, created during the explosion.
A supernova, or in the case of a smaller star, a nova.
A hypernova is a more powerful and larger explosion than a supernova. It occurs when a massive star collapses and releases an immense amount of energy, much greater than that of a supernova. Hypernovae are one of the most energetic events in the universe.

The energy output of a supernova explosion is equivalent to the energy produced by the sun over its entire lifetime.
It is not certain, but what is generally thought of as the first phase of a supernova event is gravitational collapse. The fusion reactions have exhausted fuel, and fusion is supplying less and less energy. This allow the immense gravity that has been trying to compress everything all along to begin to dominate the stellar dynamic.
No. A supernova is a massive explosion, usually from a dying supermassive star.
