Most texts would call your (2) the roundout, and your (3) the flare.
The wording can be different in different countries, in Canada it is referred to as the flare or round out.
Also in Canada we turn final...not finals.
What one aims for is changing the approach path from a descent attitude to the level attitude about fifteen feet above the surface and allowing the speed and lift to decay so as to touch down at or just above the stall.
The above can be done at any airspeed, bearing in mind at a high speed the hold off portion will be longer due to the higher speed and use up more of the landing surface before touch down.
