In 'Interstellar', the planet where the crew encounters water and giant waves is Miller, usually called Miller's planet.
The world is one of the candidate planets orbiting Gargantua, the film's enormous rotating black hole. Cooper, Amelia Brand, Doyle, and CASE land there because an earlier expedition led by astronaut Laura Miller appeared to have found a potentially habitable water world. Instead, they discover a shallow ocean, wreckage, and immense waves sweeping across the surface.
The planet's danger is intensified by extreme gravitational time dilation. One hour on Miller's planet corresponds to roughly seven years for observers farther away, so the crew's short visit costs decades back on Earth. Doyle is killed by the flooding water, and the landing party barely escapes after repairing the Ranger's engines.
The other options refer to different parts of the mission. Endurance is the spacecraft carrying the crew; Mann is the frozen world explored later; and Edmunds is another candidate planet associated with Dr. Edmunds. The waves are presented as tidal effects linked to the planet's close orbit around Gargantua, not ordinary wind-driven surf.
