You hear everything about the Sages from Rauru, Shiek, and Zelda.
No they do not know that they are sages until you pass the temples on the legend of Zelda ocarina of time 3ds.
if you mean on Zelda Ocarina of Time, then go to Ganondorf's castle
You can't explore the Chamber of Sages without hacking the game. The Chamber is simply a transition between completing the temple, seeing the Sage for that element, and returning to the outside world.
the six sages are on Legend of Zelda Ocarina of Time not Phantom Hourglass
As a character no. But in Wind Waker she is. In the room where you get the master sword, on the windows are the triforce, ganon from Oot, and the sages. There is a picture of her there.
when you put it on you can talk to the gossip stones by hitting them with your sword
Talk to zelda then find a guard and use it then and the'll let you past.
Try beating the forest temple first.
