When you beat Emerald weapon, you get master summon, master command, and master magic, right?

What about the support and independent, do they not have master summons?

Also, if you get the master materia from Bugenhagen, and then you beat the Emerald weapon, do you have 2 copies of each?

I am interested in this because I am currently playing VII and I would like to obtain the master materia this time around.
