It has 1 proton and 1 electron but free natural hydrogen is found in diatomic molecule. Hence it has 2 protons and 2 electrons

Hydrogen is an element. Its atomic number is Z=1, as you wrote.
This means that Hydrogen atom has 1 proton in its nucleus, and 1 electron orbiting around the nucleus.
In some chemical reactions, Hydrogen may lose its electron and become a positive ion: H+ (positive sign in superscript)
H+ is hydrogen atom without its electron. In other words, H+ is just a proton.
In some cases, Hydrogen atom gains an electron and becomes a Hydride ion : H- (minus sign in superscript)
H- ion contains one proton and two electrons.
However, the fact remains that Hydrogen atom consists of one proton and one electron
