ok I have no idea what's pokemon...sure its about monster that can fit inside a ball and stuff and use them in battle and such but some things I don't get it, like...

1) about pokemon breeder: what's is it, what it does, and such (important question: how do they breed skills into pokemons? or how they breed?)
2) about pokeball: I know pokeballs as big as a palm but what does small ones like the size of a pinky do? do they have similar features like the orignal sizes? can they fit very big things like gaint like pokemon?
3) about cash or money in the pokemon world: what do they call it and what it looked like?
4) about facilities and shops: what are the facilities, what they do, how many are they?
5) about pokedex: i know that it contains infomation but do they have to attack or get close to it to capture its informations?

that's kinda it for the moment so please help I don't know much and I don't have the game and I'm only reading the mangas
