What are the names of rocket stages?

Rocket stages are typically referred to as first stage, second stage, and sometimes third stage, depending on the design of the rocket. The first stage is responsible for the initial launch and lift-off, while the second stage continues propulsion after the first stage has separated. Additional stages, like the third stage, may be used for orbital insertion or specific missions. Each stage has its own engines and fuel systems, enabling efficient use of resources during ascent.
