That has nothing to do with properties of air. "Low pressure" means there isn't much pressure, it's as simple as that.
the area would become cooler with less humidity
The difference is that Low air pressure has less air molecules pushing down in one area and high air pressure has more air molecules pushing down in one area.
Normally pressure tanks come with about 30 p.s.i. pressure in them,but depending on the type of water system you may need to adjust the pressure. You always want the pressure of the empty tank to be less than the turn on pressure of your pressure switch on your pump(if you have a pump) about 5 p.s.i. less should do it.
Low pressure
This is because there is less atmosphere at higher altitudes and, therefore, less oxygen. At 5500 metres, the air pressure is half that of sea level. Around 5500 metres, is the limit for human habitation. At 8900 metres (top of Everest), the pressure is 30% of sea level. 10000 metres is the limit of the lower atmosphere. Because there is less oxygen, one has to take deeper breaths to get the same amount of oxygen.

15 PSI or less
Your blood pressure will lower because less blood will be pumped into your system by the heart
The difference is that Low air pressure has less air molecules pushing down in one area and high air pressure has more air molecules pushing down in one area.
Low pressure systems are usually associated with stormy weather and rain.
Yes as the oxygen (gas) can be compressed into the very small container which is a property.
Pressure is due to particles colliding with the walls of the container in which the system is encompassed. Therefore, for a lower pressure (with the same number of particles), the particles would have to collide less frequently with the container walls.
When there is high pressure, the air is less dense i believe
The difference is that Low air pressure has less air molecules pushing down in one area and high air pressure has more air molecules pushing down in one area.

Yes, because there is less air above you. This also explains why the higher you go, the more you become short of breath.
Gas is compressible while liquid is not. So if you get air in your brake line, which is a hydraulic system, it will not be able to exert the needed pressure on the brake pads making them less effective.
