To flow the current

Covalent substances do not conduct electricity because they are sharing electrons, hence they are in a fixed position and are not able to move around and contribute to movement of the electric current.
hydrogen ions
Atoms (and ions) are not made of compounds. Compounds are made of two or more different atoms.
When atoms lose or gain electrons, they are called ions. As electrons are negatively charged, it is when they gain electrons that they become negative ions, if they lose electrons they become positive ions. They can also form ions in pairs. for example sodium atom (NA) gives up it's outer electron and becomes an NA+ ion. the chlorine atom (CL) picks up the spare electron and becomes a CL- ion.
Plasma
Free electrons are produced at the metallic electrode that has atoms, that give up electrons, and become ions in solution.

Yes. It is made up of Na+ ions and Cl- ions.
Water (H20) is made up of hydrogen ions (H+) and hydroxide ions (OH-). When water is broken down (e.g. through electrolysis), OH- ions lose electrons to form oxygen gas and water. 4OH- --> 2H2O + O2 + 4e. The H+ ions on the other hand gain electrons to form hydrogen gas. 2H+ + 2e --> H2 Water (H20) is made up of hydrogen ions (H+) and hydroxide ions (OH-).

Oranges are made up mostly of water, which conductes electricity due to the free hydroxide ions floating around in solution
