It means that the air at the current temperature has 25% of the maximum moisture available at that temperature before becoming saturated.
Relative hunmidity is relative to the amount of moisture the air can hold at temperature.
It is relative because at higher temperature the air can hold more moisture. So at say 90F and 25% relative humidity there is much more moisture than at 70F and 25% relative humidity.

The air will be ready for condensation. The introduction of nucleation centres or a small drop in temperature will result in condensation.
what does RH% mean
if you mean air then its nitrogen.. but i dont know anything else
0.00015 = 0.015 percent
This is called relative humidity. It is the ratio between the actual humidity, and the humidity for saturated air - that is, the maximum amount of water air can hold. This saturation point is dependent on temperature.
