Evaporation of water is a process with heat absorption.
No, water and air at the same temperature of 26 degrees Celsius may feel different due to their differing heat capacities and conductivities. Water tends to retain heat more effectively than air, so while they are both 26 degrees, water may feel cooler to the touch compared to air at the same temperature.
The moving air stream from a fan increases the rate of evaporation on the skin, which can make it feel cooler. The air movement also helps to dissipate body heat, making it feel cooler compared to still air.
Body temperature is regulated by an intricate system called homeostasis. If the external (outside) temperature is hotter or colder than our body then various things come into play to maintain our body heat. If you put your hand into room temperature water (room temperature is generally accepted to be 20 degrees C) then it will feel cold, because body temp is about 37 degrees C. The water will absorb heat energy from your hand, making it feel cold, until the temperature of the water and the temperature of your hand are the same. Or until you decide that shoving your hand in cool water is pointless...If you put your hand into water that is at 37 degrees C then you won't notice any temperature difference. It just feels wet. It's really weird, try it!
Basically, the egg gets warmer as the water gets cooler until both meet at the same temperature.
We feel ice at 0 degrees Celsius as cooler than water at the same temperature because ice has a lower thermal conductivity and can absorb more heat from our skin without significantly increasing its temperature. Additionally, the phase change of ice melting into water requires energy (latent heat), which draws heat away from our skin, enhancing the sensation of cold. This means ice can more effectively extract heat from our body compared to water.

No, but it can be the same temperature if the water is spinning fast to keep it from freezing

Well, if you have 21 degrees air temperature, it's ok if the water you'll swim in is warmer, but if the water is cooler then it won't feel very comfortable. If you mean 21 degrees water temperature, it's ok to swim if the temperature of the air is warm (otherwise you'll feel cold when you come out). A heated pool's temperature is around 30 degrees, so 21 is not the same, but it's perfectly ok once you go in the water.
The water balloons will remain intact but will reach the same temperature as the cooler. If the cooler is cold, the water balloons will also be cold. If the cooler is warm, the water balloons will also be warm.
The temperature will be the same.

Melting ice stays at the same temperature until it is all melted to water.

At equilibrium the table ad air will have the same temperature. Any change in air temperature will change the temperature of the table but the change in table temperature will lag behind the change in air temperature. If you feel a table in a room it may feel cooler than the air temperature as the table material is more conductive of the heat from your skin than the air.
"Ice water" could either refer to water that has been chilled to the freezing temperature or just a container of water with ice floating in that is close to (but still above) that freezing temperature. Ice can be no warmer than the freezing point but can certainly be colder. If the solid (ice) is in equilibrium with the liquid ("ice water"), the ice will NOT be cooler, but as noted, if they are not really in equilibrium, you would expect the solid (ice) to be colder than the liquid water rather than the other way around.
