If this is the case, you're playing Pokemon Yellow. Yellow prevents the starter Pikachu from evolving due to following the anime, where Pikachu refuses to evolve (though it's possible to evolve it by trading it to another game, evolving it there, and trading it back to Yellow).
Depends what kind of pokemon. Most evolve by leveling up, some using stones (firestone, moonstone, etc) some by trading, and some by trading holding a specific item.
You have to trade with a friend at a pokemon center. I suggest trading kadabra for hunter. They will both evolve.
No you can't you have to trade with other real from pokemon green blue or yellow. Some pokemon evolve only when traded like cadabra.
In Pokemon Yellow Onix does not evolve, it is a one stage Pokemon.
You evolve it by trading it with an electirizer. It looks like a little yellow box. For all your Pokemon needs, go to serebii.net. Its a great site.
