No, the air at sea level is not always saturated. Saturation occurs when the air holds the maximum amount of water vapor it can at a given temperature and pressure, leading to humidity levels of 100%. However, relative humidity at sea level can vary widely depending on environmental conditions, temperature, and weather patterns. Thus, while air can be saturated at sea level, it is not inherently so at all times.
Sea level pressure, sometimes as mean sea level pressure.
Below sea level atmospheric pressure increases with depth. Air pressure at sea level is about 14.7 psia. Air pressure below sea level would be slightly higher.

No, air pressure is not greater at mountains than at sea level; it is actually lower. As altitude increases, the density of the air decreases, resulting in reduced air pressure. Therefore, at sea level, air pressure is higher compared to that at higher elevations like mountains.
There is not enough information to determine this. Just being at sea level does not cause the air to have a specific saturation (humidity).
To determine if the air in the room is saturated or unsaturated, you would need to measure the humidity level. If the humidity level is at 100%, then the air is saturated. If it is below 100%, then the air is unsaturated.

The air pressure is greatest at sea level.
Below sea level atmospheric pressure increases with depth. Air pressure at sea level is about 14.7 psia. Air pressure below sea level would be slightly higher.

At sea level
The average air pressure at sea level is around 101.3 kilopascals (kPa).
Air pressure in a valley below sea level would be higher than at sea level. This is because the weight of the air column above is greater in the valley due to the higher density of air molecules compressed into a smaller volume.
The air pressure at sea level is typically around 1013 millibars or 29.92 inches of mercury.
