Three - the two drive axles, and the steer axle.
A truck with three axles,(1 steering and 2 drive axles) is called a tandem.A trailer with 3 axles is called a tridem or a triaxle depending on the spacing between the axles.Number of axles is not specific to any one manufacture.
6x4 has three axles, and two of them are live axles. 4x2 has two axles, and only one is a live axle.
You have to put your weight evenly between your trailer axles and your trucks rear axles. You have to know the weight limit of your truck and trailer, it should say in the owner's manual or you can read the weight limit on the tires. The majority of the weight should be on the trailer because if you put most of the weight on the truck the trailer will begin to fishtail. If it is a flatbed trailer and you look along the side you will see that it bows up, you should never load it to were it bows down because it is probably overloaded at that point. Also you should read the owner's manual to learn how to move the axles on the trailer.

Three or more. I've run units with 21 axles before. A typical line haul truck has five.
usually somewhere between one and three. Do you have power windows?
Depending on the style and manufacturer, two or three, but usually two.
A truck with three rear axles and one of the axles is a drop axle that is only used when carrying heavy loads.
