What is Controllable Pitch feathering propeller?
It is a propeller in which blades can be angled to improve efficiency. This was discovered in the 1930's and helped immensely in development and speed of fighter aircraft in WW2.
Can a ship's propeller having four controllable pitch propellers be replaced with two blade propellers?
It is possible to replace one kind of propeller (sometimes called a screw) with another kind. When moving to the "less complex" two blade propeller, the mechanisms that control the pitch of the blades of the propeller with pitch control will be abandoned or removed. There may be a lot more to this, but the basic answer is that you can replace one kind of propeller with another kind, as long as the "handedness" of the screw is the same as the one coming off. Or you'll go backwards in "Ahead" and ahead in "Back" on the direction selector.
What is the formula of propeller pitch?

What is the pitch of the prop on a submarine?
It varies by design. I'm not sure the specifics are going to be available to the general public, as such things are usually classified. And note that most current vessels run a controllable variable pitch propeller, which means the actual pitch can be varied through a range of angles.
