stomata
During the hottest time of the day, plants usually close their stomata to reduce water loss through transpiration and to prevent wilting. This helps them conserve water and maintain turgidity.
Plants can close their stomata to reduce water loss during times of stress using mechanisms like the accumulation of ions that cause osmotic changes, as well as the production of abscisic acid which signals stomatal closure. Additionally, certain plants, like succulents and CAM plants, have specialized adaptations that allow them to limit water loss by keeping their stomata closed during the day and opening them at night.
During mid day when the intensity of light and day temperature is higher
In desert plants, the stomata is open during night. During night, desert plants (also called xerophytes) absorb co2 and form an intermediate. Then during day time when the stomata is closed to prevent loss of water, they use this stored carbon dioxide to perform photosynthesis.

stomata
When the stomata in a leaf close during the day, it helps to reduce water loss through transpiration and conserves water within the plant. However, it can also limit the entry of carbon dioxide for photosynthesis, potentially slowing down the plant's growth and metabolism.
Cam plants close during the night and open during the day because they are photosensitive and respond to light. To do it experimentally, try with a torch for some time.

at night when there is little to no light.
Stomata are typically open during the day to allow for gas exchange, such as photosynthesis (uptake of carbon dioxide and release of oxygen). They usually close at night to conserve water and prevent excess water loss through transpiration.
Stomata do not occur - during the night or day. Stomata are physical features of leaves: they are there from when the leaf is created to when it dies.

Xerophytes are plants adapted to survive in arid environments with limited water availability. Their adaptations include thick, waxy cuticles that reduce water loss, deep or extensive root systems to access moisture, and modified leaves, such as spines or reduced surface area, to minimize transpiration. Some xerophytes also have specialized photosynthetic processes, like CAM (Crassulacean Acid Metabolism), which allow them to conserve water by opening their stomata at night instead of during the hotter day. These features enable them to thrive in harsh, dry conditions.
