Glass of water sweating is a physical process caused by condensation of water vapor from the air onto the cooler surface of the glass. It does not involve any chemical reactions.
Transpiration.
Yes, humidity in the air is considered a physical change. It refers to the amount of water vapor present in the air, which can vary with temperature and other conditions. This change in moisture content does not alter the chemical composition of water; it merely changes its state from liquid (in the form of droplets) to gas (water vapor). Thus, the process of evaporation and condensation associated with humidity is a physical change.
The rising of hot air over a radiator is a physical process. It is due to the difference in temperature between the heated air near the radiator and the cooler air in the surrounding environment. As the air near the radiator becomes warmer, it expands and becomes less dense, causing it to rise and be replaced by cooler air. This process, known as convection, is a form of heat transfer.
The humidifier putting moisture into the air is a physical change. It involves adding water vapor, which is a change in the physical state of water from liquid to gas, without altering the chemical composition of the water molecule.

The process of taking in air or water involves the contraction of muscles around the lungs or gills to expand the cavity and create negative pressure, allowing air or water to be drawn in. In mammals, this is facilitated by the diaphragm muscle contracting and expanding the chest cavity. In aquatic animals, gills create a similar negative pressure to draw water in and facilitate gas exchange.

Transpiration.
When you say that there is moisture in the air it pretty much means water in the air.It is a physical change, as no new products have been formed.
Clouding is a purely physical process of condensing vaporous water into liquid water (also freezing or sublimating it to solid ice / hail / snow) . Chemically nothing has changed (water molecules stay unchanged, still being water) only there (physical) state (this is a kind of 'condition' of matter) has changed.

When you breathe in air, the process is called inhalingor inhalation.Breathing out is exhaling, and the overall process is known as respiration.

Evaporation is the process where water moves from the air to the land.
