The two main types of rocket engines are Solid fuel rocket engines and Liquid fuel rocket engines.

As regards the main engines on the rocket, there is an ignitor associated with each rocket motor. An internal "blowtorch" of fuel and oxidizer in each engine is ignited with spark plugs.
It depends. Some rocket engines have a single stage, some have 3 or more. Staging allows for the overall weight of the vehicle to be reduced by dropping off parts of the rocket and continuing on with smaller rocket engines and less fuel.

Rocket engines are not air breathing engines and hence they can be propelled into space.
Rocket engine
The Saturn V rocket had five rocket engines in its first stage, called the F-1 engines. These engines were responsible for providing the necessary thrust to lift the rocket off the ground and into space.
Inside a rocket, you will typically find a payload, which is the object the rocket is carrying into space. This could be a satellite, a spacecraft, or scientific instruments. Additionally, there will be a propulsion system, such as engines and fuel tanks, that provide the thrust needed to propel the rocket into space.
Model rocket engines are reproductions of rocket engines that are scaled down to a much smaller size than the real thing. They usually don't do anything and are for display purposes.

A rocket ship takes off by igniting its rocket engines, which produce thrust that propels the ship upward. The force generated by the rocket engines pushes the ship off the ground and into the air, overcoming Earth's gravity. As the rocket ascends, its engines continue to provide thrust to propel it further into space.
