Pulmonary valve stenosis
I guess you refer to the pulmonary valve stenosis which usually is due to the valve calcification when less blood supply will go from right ventricle of heart to the pulmonary circulation. The right ventricle will be hypertrophied because it's working harder then before.

Pulmonary stenosis is often caused by congenital heart defects where the pulmonary valve is abnormally narrow. This narrowing restricts blood flow from the right ventricle to the lungs, leading to increased pressure in the right side of the heart. Pulmonary stenosis can also be acquired later in life due to conditions like rheumatic heart disease or infective endocarditis.

Pyloric stenosis is also referred to as hypertrophic pyloric stenosis
Yes
Because pulmonary fibrosis causes hypoxia which further aggravates pulmonary edema & hence pulmonary hypertension which further increases the back pressure thus ultimately leading to more complicated mitral stenosis.
