I'm not clear with it.

Vy= best rate of climb speed

Vx= best angle of climb speed

Va= manouver speed (memory is fuzzy on this but I think it is the maximum speed at which an abrupt control input can be made)

POH= pilots operating handbook (pilots manual)

There is only one interesting speed - Vne

You are 99% correct, it's the indicated airspeed limit for full control deflection. Above that speed, using full control deflection can overstress the airframe.
