The human skin cell shedding rate (called the desquamation rate) depends on factors such as the location of the skin being considered, the total area being considered, and the person's age. Even keeping the skin location, skin area, and age constant will result in different rates for different individuals.

and Table 2 in particular.
As an example, if we take the average rate of all subjects and all sample areas given in the Table 2 referenced above, we obtain an average rate of 945 cells per square centimeter per hour. Let's assume 945 cells per square centimeter per hour is close to the average desquamation rate for the entire body even though it depends on location and the table gives actual rates that vary from a low of 530 to a high of 1856. There are 10,000 square centimeters in a square meter. Average adult humans have a skin area of somewhere between 1.5 and 2.0 square meters. This means the average adult human has somewhere between 15,000 and 20,000 square centimeters of skin. Multiplying this area by the average of 945 cells per square centimeter per hour gives us
14,175,000 to 18,900,000 cells per hour

How many Epidermis cells do you lose every day?
I think none, because Epidermis cells are on leaves.
Three cells with generation times of 30 minutes are inoculated into a culture medium How many cells are there after 5 hours?
The short answer is 3072. You get this answer by using the following formula. Initial # of cells X 2Number of Generations = Number of Cells 48 cells
How many living and nonliving cells are there on earth?
It is impossible to tell how many cells are living and not living. There are a ton you would have to count....which would take forever!!

How many calories do you loose from eating?
You may think this answer is crazy but up to a hundred that is the same with kissing. How ever long you take to eat that is how many calories you lose, so lets say you take up to 20 minutes to finish a huge burger you would lose 20 calories. Here is another example if it takes you ten minutes to finish a salad then you would lose ten calories.
