Two - one warm and one cold. An occluded front is formed when the cold front 'wraps around' the warm front.
Usually, a stationary front has two air masses. It becomes a stationary front when two different air masses are too weak to replace the other. A wide variety of weather can be found along a stationary front.
Tornadoes are more likely to form along a cold front, but they can occasionally form along a warm front. Many tornadoes form in an area called Larko's triangle, between a warm front and cold front. Some tornadoes form along a dry line, and in fact a try line can be more proficient at producing tornadoes than a cold front. Still other tornadoes form from tropical systems, which do not involve any sort of front.
Many types, including stratocumulus, nimbostratus, and cumulonimbus.

an air mass is a small volume of air defined by its temperature and water vapor content. Air masses cover many hundreds or thousands of square miles, and adopt the characteristics of the surface below them. They are classified according to latitude and their continental or maritime source regions. Colder air masses are termed polar or arctic, while warmer air masses are deemed tropical. Continental and superior air masses are dry while maritime and monsoon air masses are moist. Weather fronts separate air masses with different density (temperature and/or moisture) characteristics. Once an air mass moves away from its source region, underlying vegetation and water bodies can quickly modify its character. Classification schemes tackle an air mass' characteristics, and well as modification...

Usually two, but sometimes it can be three.
Warm front--rise in temperature; gentle rain; longer duration Cold front--drop in temperature; violent precipitation including storms; shorter duration Stationary front--many days of precipitation along the frontal boundary Occluded front--precipitation
there are four: cold, warm, occluded, and stationary

Air masses are categorized by their humidity and temperature. Fronts are a boundary that forms when air masses meet.Cold Front*as cold air moves forward, warm air is pushed upward*cold air mass displaces a warm air masscumulus and cumulonimbus clouds formUsually produce thunderstorms with heavy percipitationMove into regions quicklyBreif, heavy storms are likelyAfter storms, the air is cooler and often very clearWarm Front*warm air gradually moves up and over a mass of denser, colder air*warm air mass overtakes cold air massnimbostratus clouds formconstant rain/snow (for at least 24 hours)move more slowly than cold frontsbring many hours of steady rain/snowAfter the front passes, it is often warmer

Jupiter is about 317.938 earth masses.
Many types, including stratocumulus, nimbostratus, and cumulonimbus.
A cold air mass originates over water or land that is colder than the air temperature at the time. Cold air masses usually originate in the northwest and travel eastward. A warm air mass is formed from warm water or ground temperature that is warmer than the air at the time. Warm air masses usually originate in the southwest and travel east or northeast.
There are three different types of air masses.
There are two types of air masses: COLD AIR AND WARM AIR.Cold Air Masses-Cold air masses can cause thunderstorms and even tornadoes.Warm Air Masses-Warm air masses can bring many hours of steady rain and snow.
