by completing all the gym battles in johto( then finding the dragon fang) and you will get a phone call from prof elm,fly to his lab,then he will give you a master ball,to get more balls equip a Pokemon with a master ball and duplicate that Pokemon
there is no master ball in diamond and also great ball. but there is silver ball-silver ball is like a master ball.

You can't have unlimited master balls although u can give the master ball to a Pokemon and duplicate it at battle frontier
You can't but if you're really desperate, you can hack the game.
just throw your master ball away

Professor Elm gives you the only master ball in the game.
Use A Master Ball Or Ultra Ball To Catch. But I Think It is Hard To Find Master Ball...:/
