Our sun produces mostly helium by fusion, but it also uses fusion to make lithium, beryllium and boron. Temperature and mass determine how far a star can go with fusion. "Solar fusion" only refers to the fusion going on in Sol, the star nearest Earth (our star, the sun). Stellar nucleosynthesis is how elements are produced in stars, and in much larger & hotter stars fusion is responsible for elements as heavy as unstable zinc, or stable iron.
Our sun mostly transforms hydrogen nuclei into helium by fusion, but it also fuses helium with helium, lithium with hydrogen, and beryllium with hydrogen, to make elements as heavy as boron.
None, it is not possible for fusion to occur on the sun's surface. It is much too cold.
Helium. Almost all fusion taking place in the Sun is hydrogen fusing to helium.
Hydrogen
the sun is made from helium and hydrogen fused together by gravity
None. The sun is made of pure elements, mostly hydrogen, which fuse together, creating energy in the form of heat and light. When the hydrogen has fused into helium, the helium fuses into the heavier elements. Eventually, a couple billion years in the future, the sun will be made almost entirely of iron, at which point the fusion will cease and the sun will DIE. But you won't be around to see it. At no point does water form without it being immediately consumed and fused into heavier elements.
Both energy (sunlight) and helium are produced when hydrogen fuses together. This also what happened when the US used atomic weapons on Japan in WW2.
In a process known as nuclear fusion, hydrogen is constantly fused into helium.

Within our Sun, hydrogen is fused into helium at very high temperatures. This is how the Sun is powered.

It is just protons joining together, which are hydrogen ions, so the only fuel required is hydrogen, the reaction proceeds due to the high pressure at the sun's core, due to the immense gravitational compression. See the link below
Hydrogen atoms fuse to form helium and energy.
The back parts don't seem to be joined together.

It is a compound, as it is a collection of different elements fused together by molecular bonds.
A compound. (Could also be a mixture depending on if they are fused together or mixed)

None of the koala's fingers are fused together. The second and third toe of the koala's hind feet are fused together.
