If the entire area is flooded with, say, 20 inches, will the water perculate up through the ground and flood your property or will the sandbags keep the water out.

The water will percolate through the sandbags AND up through the ground, but they will buy you the time you need to pump it to the outside. A better solution is to put a retention pond near your house, and use the soil from that to create a berm, with a gentle enough slope for you to go over with your lawmower. It will save you from having to fill so many sandbags when it comes time to do something about a flood. You can make a steeper berm and let it overgrow, and have yourself a privacy barrier -- that's what I did.

Depends on the composition, permeability and compaction of the ground inside your sandbag perimeter, and how long you need to keep the water out.
If you're sitting on mostly sand or gravel, I imagine it won't take much time for the water to start filling your ramparts. If you're on thick clay or bentonite, it might hold for a long time.
Eventually, though, the water will probably trickle through the sandbags even if your ground is watertight. The sandbags won't hold forever.

It depends on how long the area stays flooded and the saturation level of the ground surrounding the house. If the floodwaters remain for a long period of time you will eventually get seepage through the sandbags and up through the ground as it reaches it's saturation point.
