Which V speed corresponds to the maneuvering speed?

The speed that corresponds to maneuvering speed is Va. Maneuvering speed is the maximum speed at which full deflection of the flight controls can be applied without risking structural damage to the aircraft. It is specifically designed to provide a buffer in turbulence; if the aircraft encounters unexpected turbulence, the pilot can safely use full control inputs without exceeding the aircraft's load limits.

Va is calculated based on the aircraft's weight and is lower than the maximum structural cruising speed (Vno) but higher than the stalling speed in the clean configuration (Vs). This range of speeds helps pilots maintain control authority while also protecting the aircraft from excessive forces. Pilots are trained to be aware of maneuvering speed, especially when operating in turbulent air or when performing defensive maneuvers.

The other speeds mentioned in the question serve different purposes: Vs is the stall speed, Vy is the best rate of climb speed, and Vne is the never exceed speed. Each serves important functions in flying, but only Va provides the safety margin needed for maneuvering control without compromising the structure of the aircraft.
