When you give the order for a Ghost to Nuke a certain area with triggers, is there a way for more then 1 Nuke to launch at the same time with just one ghost? The reason why I want to know this is cause, it would kinda confussing having tons of ghosts to fire nukes in one area... Especially if you are using the ghosts for something else.
Not that I am aware of, no.
Well ghost in the actual game only fire 1 nuke at a time...
But if your problem is so it can do more damage then you can use the bring nuke conditions and set the units/buildings there to a certain ammount and let the nuke do the rest of the damage.
Uhm... on a side note to this question... using the Stacking Units trick, would you be able to stack up ghosts on top of each other and then have them nuke something? Then kill off the extra stacked ghosts?
I think so, but I am not toally sure.
It also might work (in theory) to remove and replace the ghost speedily, each time right after it nukes, thus getting nukes very close to one another. (Remove the ghost as in move it to somewhere else, then put another one in it's place.)
It still has to be able to target the area, I think, or the nukle is called off (unless nuke is already visible and falling).
Don't say I think when you know it's true

It makes it sound like you don't know.
Don't be afraid to be wrong because we will correct you ASAP

OOO..ooo! That struck another thing in my mind! Hey, if you can move units and such, does this mean you can move a ghost to a completely different side of the map WHILE it is in the midst of nuking?
Yes, and it's been done in a few maps.
It isn't that bad using one ghost per nuke, is it?
If normal ghosts are being used, try any one of the large number of hero ghosts
