Cereals should be included in a horse's diet in small amounts and should be primarily used as a supplement to their main diet of forages like hay and grass. It's important to choose high-quality cereals that are easy for horses to digest, such as oats, barley, or corn. Cereals should be fed in divided portions throughout the day to prevent digestive issues.
Given a choice, horses, whether wild or domesticated, prefer eating in herds.

This depends on what you mean by 'cereals'. If you mean cereal grains, then a horse can eat oats, corn, wheat, barley, etc. If you mean breakfast cereals, then a horse Can eat Cheerios, but it is not recommended to feed them any more than a handful due to the sugar content.
All horses, no matter what breed prefer to live in a group called a herd. However some horses may prefer to be alone, though this is uncommon.
Zebras are like horses. Horses do not prefer snow, neither do Zebras.
