When you get the moldy cheese from the castle dungeon, throw the wall switch that opens the rear gate to the cell. Later, you can enter through the tunnel from Mordred's lab.
You don't. Once you have gotten the cheese, and pulled the wall switch, that is all you can do there. You will have to enter the dungeon from Mordred's underground lab, through the tunnel he dug to escape. (see the related question)
The wall to the left is just dirt, and you can push through it. At the end of the tunnel is the back gate to the dungeon (if you pulled the switch in the library, it's open). You will need Merlin the Owl to go with you. (see the related question)
In Mordred's underground lair, there is a way blocking the tunnel to the back of the dungeon. But it isn't rock, only dirt, and can be pushed through will a little effort.
You can't.

Merlin the Owl cannot go to the castle until after the end of the game. You can push through the dirt wall in the lab. The tunnel leads to the dungeon cell.
