Severely over simplifying things:
In a fission bomb ultra isotopicly pure Uranium-235, Uranium-233, and/or Plutonium-239.
In a fusion bomb lithium and deuterium (heavy hydrogen) in the form of solid lithium-deuteride.
Uranium hexafluoride (hex) is a compound of uranium that becomes a gas when heated. In gaseous form, it can be "enriched". Enriched uranium is needed for research reactors, most non-Canadian power reactors, and bombs.
Plutonium is used as the fissile material in the core of a nuclear bomb. When a critical mass of plutonium is rapidly brought together, a chain reaction occurs, releasing a large amount of energy in the form of a nuclear explosion.
Plutonium is the metallic element used in nuclear weapons. It is highly fissile, meaning it can undergo nuclear fission and sustain a chain reaction in a nuclear bomb.
The discovery in the ashes of the first H-bomb was the element einsteinium. This element was created during the nuclear fusion reactions that occurred in the bomb. Einsteinium is a synthetic element named after physicist Albert Einstein.
A nuclear bomb is any bomb with any nuclear or atomic material inside it, while a plutonium bomb is a specific type of nuclear bomb. Plutonium could be the nuclear material inside the bomb, and if it is, it's a plutonium bomb.

A nuclear bomb contains a radioactive element that is caused to react at a certain time, so technically no.
I doubt the movie says.
An atomic bomb is a complete deliverable bomb, including all nonnuclear components. The nuclear core is a rather small part, typically between 2 to 3 inches in diameter that contains the fissile fuel that when made supercritical by conventional explosives in the bomb fissions and provides the energy to drive the actual nuclear explosion.

Highly unlikely if not altogether impossible. In a core meltdown, you might see a steam explosion if the core melts and breaches the containment structure and hits say cooling water. But even a runaway chain reaction in a reactor would not cause a nuclear explosion like a bomb.

there were two types of nuclear bombs. A "gun type" bomb and an implosion type one with a plutonium core

The reflector in a nuclear weapon core is made of a material which can reflect neutrons from fission in the core back into the core, instead of wasting them. A tamper can permit a smaller mass of nuclear fuel (an unreflected subcritical mass of nuclear material can quickly become critical if a reflector is used). Depending on the material, they can also have a neutron-moderation effect. The tamper in many nuclear weapons is also the reflector.
