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.
3 main liquid fuel engines, 2 solid-stage rocket boosters, and 25 compressed gas thrusters for maneuvering.

The engine are classified based on combustion (ignition), fuel used, cooling, application and constructions. Based on the combustion type : 1. External combustionengines and 2. Internal combustion engines Based on fuel used : 1. Diesel engines, 2. Petrol engines, 3. CNG engines and LPG engines Based on cooling system : 1. Air cooled engines and 2. Liquid cooled engines Based on applications : 1. Statinary engine 2. Rocket engine and 3. Automobile engine Based on construction : 1. Inline engines, 2. Opposed engines, 3. Rotary engine, 4. V-engines and 5. W engines
The Boeing 747 uses four engines.
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.
5 J-2 Engines
The first stage of the Apollo rocket had about 7.5 million pounds of thrust, generated by five F-1 engines. This massive amount of thrust was needed to launch the rocket and overcome Earth's gravity.
An Apollo rocket had three main stages: the first stage contained the engines to lift the rocket off the launch pad, the second stage provided additional thrust to reach orbit, and the third stage was used to propel the spacecraft to its destination in space.

It gives the initial boost to get the rocket off the ground, as the fuel burns up it empties the stage, so to get it into space the first stage ejected to lighten the load and the second stage ignites. and so on. This is an almost out dated system, but occasionally it is still used.
The Apollo 11 rocket had three stages: the first stage with five F-1 engines, the second stage with five J-2 engines, and the third stage with one J-2 engine. These stages were designed to provide the necessary thrust to propel the spacecraft into Earth orbit and then on its trajectory to the Moon.
There were eleven main engines on the Saturn V. Five on the first stage, five on the second stage and one on the third stage. This does not count the engine on the lunar lander. How do I know? I worked as an Aerospace Engineer on the first stage of the Saturn V during Apollo. My partner and I were the ONLY two women working on the Saturn V.

Because it's moving a smaller mass. The first stage of the rocket has to move the whole vehicle. By the time you're ready to fly on the third-stage engines, you've burned up the fuel in the first two stages and separated from them.
Just 1, although it had multiple stages. To Clarify The Saturn V Rocket is a 3 stage rocket system as the Americans like to say The First stage had five individual main thrust engines Second had three Third stage had one
