Helium fusion is a process that happens as a part of what is called stellar nucleosynthesis. That's a term we apply to the mechanisms working within stars. Stars are fusion engines, and they are powered primarily by fusing the element hydrogen into the element helium (the first and second most abundant elements in the universe, respectively). This process sometimes goes under the name proton-proton reaction. As stars exhaust their hydrogen fuel and build up a lot of helium, they begin to fuse the helium together to form the element carbon in what is called the triple-alpha process.

Fusion is any reaction where the nucleus of atoms join together. Joining of hydrogen is an example of nuclear fusion.
I'm not sure what you are asking, but atomic fusion is a process by which two atoms are forced together to form one larger atom. This is the process that drives the sun where it is mostly fusing two hydrogen atoms into one helium atom. Fusion reactions can also occur here on Earth in a hydrogen bomb explosion or in a particle accelerator where atoms are smashed together at great velocity and occasionally stick together to form new atoms. This is basically the process by which transuranic elements are created.
No. Hydrogen fusion occurs in the star's core.
Nuclear fusion is caused by a huge amount of energy being absorbed by two atoms that are close to each other and they fuse, or under go fusion to give of that energy. The byproduct of the process is roughly equivalent to the amount of energy that was absorbed by the original two or more atoms.
Not enough pressure or temperature.
fusion
yeah
When two hydrogen atoms fuse to become one helium atom.
nuclear fusion is not a natural occurrence, it is when two atoms are fused together

Fusion is putting together (atoms ... usually hydrogen atoms), Fission is the breaking apart of atoms. And fusion requires high energy to occur because it requires the nucleus of atoms to touch (collide) - not an easy thing to do (basically impossible using only chemical energy).
The sun and other stars are hot enough and dense enough at their cores for nuclear fusion to occur. Hydrogen atoms fuse together into helium atoms, releasing a tremendous amount of energy in the process.
No. Hydrogen fusion occurs in the star's core.

When hydrogen stocks run out
The fusion of Hydrogen into Helium.

In the cores of stars and hydrogen bombs.
