From the Lottories.
you cant
There is only one masterball in yellow.

You can only get another masterball if a friend trades you a Pokemon holding the masterball they obtained.
Recieve it from Elm after beating the Elite 4
You can't. You only get one without trading it from another Pokemon game.
You can't. Unless your using Pokemon emerald. don't use the masterball on rayquaza. when you beat the Pokemon league clone a Pokemon holding the masterball. Wow i never even thought of that! thanks!
You can get another masterball by winning the lottery with every single number.
In Pokemon lottery corner in every Pokemon game if ALL the digits of the lottery matches exactly in one of your Pokemon then you will get a masterball for a prize(it is very difficult though).
Have it traded from another game.. that's about it
