Tag (also referred to as lift) axles allow more weight to be carried, by creating more of a contact surface with the road for weight to be distributed on. When it's behind the drive axle(s), it's a tag axle; when it's in front of the drive axles, it's a pusher axle.
Some companies set up tandem axle trucks where the rear drive axle is a tag axle, so that it can be lifted up to shorten the turn radius of the tractor. Schneider National used to have some Freightliner Argosy COEs which were set up this way.
In Europe, the use of a tag axle doesn't increase the amount of weight which can be totaled, but their use is encouraged because it puts less stress on the roadways than a 4x2 tractor.
Tag axles can be somewhat problematic - especially on a single axle truck - in that they effectively can turn the drive axle into a fulcrum, placing extra weight on the steer axle.
However, in many states, total allowable gross weight is determined by vehicle wheelbase, and tag axles may be used rather than pusher axles because they effectively extend the vehicle's wheelbase, thus allowing a higher gross weight.

What is the difference between a pusher axle and a tag axle?
a pusher axle is in front of the drive axles, a tag axle is behind them
What is the purpose of a pusher axle on a dump truck?
It allows more weight to be carried. Bear in mind, it's only a pusher axle if it's located in front of the drive axle(s) - if it's behind, then it's a tag axle.

A quad axle dump truck is a tandem axle dump truck, with additional lifting pusher and/or tag axles. The most common configuration is two steerable lift axles in front of the drive tandems, although some will have one pusher in front of the tandems, and a tag behind the tandems.

Does tag axle switch need to be on outside of cab on dumptruck?
No. In fact, I've never operated a dump truck (or any other vehicle with a lift axle, for that matter) where the knob to raise and lower the lift axle was not in the cab.
Is there a semi truck with two axle's but has only one drive axle?
You mean with tandem axles, or with just two axles total? In the case of having two axles at the rear, yes. This is pretty common in Europe, where a standard 2x4 tractor will have an additional tag or pusher axle in order to reduce wear on roadways. In the US, it isn't so common, but it's not unheard of. I know Schneider National used to run some Freightliner Argosy COEs which had a single drive axle and a tag axle behind it.. when backing, the driver could raise the tag axle, and it would shorten the overall wheelbase of the power unit, allowing for tighter turns to be made.
