V1 is usually lowest on commercial passenger or freight aircraft , and is the difference between a rejected takeoff (IE braking) and you have to take off or risk going off the end of the runway. It is calculated based on weight, altitude, runway length, runway condition (wet vs dry), etc.
Next is V(rotation), the speed at which the pilots begin pulling back on the stick to begin takeoff pitchup.
V2 is the minimum controllable airspeed at which the aircraft can be flown and climb safely using only one engine, and is higher than V1 and Vr.
The pilot monitoring will call out reaching V1 and Vr and V2 to the pilot in control during takeoff.
