$(a)$ Cancer: Non-communicable (caused by genetic mutations or environmental factors,not pathogens).
$(b)$ High blood pressure: Non-communicable (a lifestyle or physiological disorder).
$(c)$ Common cold: Communicable (caused by viruses,spreads through droplets).
$(d)$ Diabetes: Non-communicable (a metabolic disorder).
$(e)$ Tuberculosis: Communicable (caused by bacteria,spreads through air).
$(f)$ Night blindness: Non-communicable (caused by Vitamin $A$ deficiency).
$(g)$ $SARS$: Communicable (caused by a virus,spreads through respiratory droplets).
$(h)$ Typhoid: Communicable (caused by bacteria,spreads through contaminated food/water).
$(i)$ Cholera: Communicable (caused by bacteria,spreads through contaminated food/water).
