Lung capacity can not be increased by a disorder.
Take deep breaths.
Yes, you can increase your lung capacity when you grow. When your grow you need more air, so your lungs grow with you. The taller you grow the more air you need!
Yes. The amount of air that we breath in depends on our weight. If you increase your muscles then your lung capacity increases side by side. But when you get fat, your lung capacity does not increase proportionally and you will end up doing more number of respirations than a normal person to get in the required amount of oxygen.
Pranayama helps to increase your lung capacity.

On average, a person uses about 10-15% of their lung capacity during normal, relaxed breathing. This is known as tidal volume, which typically ranges from 500 to 600 milliliters in adults. During physical activity or deep breathing exercises, lung capacity can increase significantly, allowing for greater oxygen intake. Factors such as fitness level, lung health, and body size can affect how much lung capacity is utilized.
Diseases that can lead to a small vital capacity include chronic obstructive pulmonary disease (COPD), neuromuscular disorders such as muscular dystrophy, and restrictive lung diseases like pulmonary fibrosis. These conditions can result in decreased lung function and reduced ability to fully inflate the lungs, leading to a smaller vital capacity.
The lung capacity vary on the person's age, gender, where he lives and more. For example, if he lives in a smoke-free area his lung capacity is probably more. The average lung capacity for a human is 4-6 liters of air and the average lung capacity for a 10-11 year old is around 4 liters.
Lung capacity varies from person to person. The part that matters is whether or not a person is using all of their lungs. If they are not, they are at risk for pneumonia, or fluid and bacteria filing the alveoli in the lungs. Also, when a person smokes, they damage alveoli, causing the lung to not be able to use their entire capacity. This forces the lungs to work harder to make up for the areas that they are not able to use.
