You can only get lots of master balls by using a cheat/code. There is only one or two in the actual game
You cannot find a second master ball however you can trade Pokemon to get another Pokemon with a master ball or use an action replay
There is only one Master ball in Pokemon diamond so use it wisely. I hope you can find it!
you get the master ball after beating cirus and others
From Cyrus after you beat him at the Galactic Veilstone Building (4th Floor)
soon enough youll venture through a dark cave and at the end there is dialga you will have a master ball by then use the master ball to catch dialga
no not unless you trade a Pokemon who is holding a master ball that's what I did because I had diamond and pearl i just reset and start from beginning with pearl until I get master ball then repeat. So far I've got 79 hope this helps
you could go to the veilstone shopping center[.P.S it is the big building not with spikes.]
The only way to get another master ball in Pokemon dimond whithout cheating is by giving a Pokemon a master ball as an item in another game and trading that Pokemon to your Pokemon dimond game and take the master ball then you can use it. Or you can get an action replay at www.amizon.com for $20.00 and find the master ball cheat for it then you can get lots of master balls all the time it realy works try it.
get an action replay and find a cheat for it (i forget what it is called) but there are 2 types, heart scale and master ball. i prefer the heart scale cheat.

no
only if you buy an action replay and get the wild Pokemon modifier code... sorry- i used a master ball :(
