It is not specifically those elements which "produce stars". Whatever elements happen to be around clump together, through gravity, and form the star.
Nuclear Fusion
Stars play a variety of roles. First and foremost, the sun is a star. It provides the heat and light necessary for life of Earth. Stars also create most of the elements we find. Before stars started forming all matter in the universe consisted of hydrogen, helium, and trace amounts of lithium. All other elements have since been made in the thermonuclear furnaces of stars.
No, stars do not reproduce in the same way plants or animals do. Stars form from a process called stellar nucleosynthesis, where elements are fused together in their cores. They do not have the ability to reproduce like living organisms do.
The main fuel for red giant stars is helium. In the core of red giant stars, hydrogen fusion has ceased, and as the star evolves, it starts fusing helium into heavier elements like carbon and oxygen. This process produces the energy that sustains the star's outer layers and causes it to expand and cool, creating a red giant.
That is called "nuclear fusion".
The stellar process in which the fusion of hydrogen produces other elements is called nucleosynthesis. This is a key process in the evolution of stars, where lighter elements such as hydrogen and helium are fused together to form heavier elements like carbon, oxygen, and iron.

Nuclear fusion is the process that produces energy in the stars, including our sun

Nuclear Fusion
fusion reactions in stars
No elements were formed in the big bang. After quite some time, hydrogen began to form, and it is the main constituent of stars. The main by-product of nuclear fusion in stars is helium.
Stars obtain energy through the majority of their lives by the process of thermonuclear fusion of the nuclei of light elements to produce nuclei of heavier elements. Initially the processes fuses hydrogen nuclei, producing helium nuclei (similar to what hydrogen bombs do), but the process ceases when it produces nickel and iron nuclei at which point the star begins dying as it has run out of nuclear fuel.
That process is known as nuclear fusion. In nuclear fusion, lighter elements such as hydrogen combine to form heavier elements, releasing energy in the process. This is the process that powers stars like our sun.

Fusing hydrogen atoms into heavier elements produces helium and releases a large amount of energy in the form of heat and light. This process, known as nuclear fusion, occurs in the core of stars like our sun and is responsible for the sun's energy output.
