They are just common names for different ship classifications.
Corvette: A corvette is a small, maneuverable, lightly armed warship, originally smaller than a frigate (2000+ tons) and larger than a coastal patrol craft or fast attack craft (500 or fewer tons), although many recent designs resemble frigates in size and role. During the Age of Sail, corvettes were smaller than frigates and larger than sloops-of-war, usually with a single gun deck.
Frigate: A frigate is any of several types of warship, the term having been used for ships of various sizes and roles over the last few centuries.
Cruiser: The term "cruiser" or "cruizer" was first commonly used in the 17th century to refer to an independent warship. "Cruiser" meant the purpose or mission of a ship, rather than a category of vessel. However, the term was nonetheless used to mean a smaller, faster warship suitable for such a role. In the 17th century, the ship of the line was generally too large, inflexible, and expensive to be dispatched on long-range missions (for instance, to the Americas), and too strategically important to be put at risk of fouling and foundering by continual patrol duties.
