no you would be in a 100% humidity environment.

If the water level is truly unchanged, either evaporation did not take place or some one added a small amount of water to bring the level back to the earlier level!
If the dish is closed with a lid which is airtight, obviously the water vapor above the liquid cannot escape outside and the level remains unchanged.

No, the water level will definitely decrease from day to day. It could just be that the dampness of the air is really high. Even if it is really damp, evaporation can still happen. For example, it may be snowing but your clothes would still dry up. You may not believe it as the evaporation happens at a really low rate.
When you put a cup with ice cubes into the freezer, condensation can still happen. But it is not noticable as the little droplets of the water would be frozen too when you inspect it.
I hope this helps.:)

It is the case of saturated vapor pressure over water.
Amount of water evaporated and condensed every instant of time is same and same for said time. Therefore, there is no change of water level on the dish.
