Yes, you can.
You use a regular bread recipe and substitute half of the flour with whole wheat flour.
Grind whole wheat kernels into flour. Use this flour in your bread recipe and you're set! 100 percent whole wheat means you use 100 percent of the wheat kernel.
It depends on which brand you are talking about look at the nutrition facts and it will tell you how many calories a slice has. Make sure you are buying 100% whole wheat bread.
An answer requires more information. It would depend on whether the bread is commercially baked, baked at home from a recipe, what kind of wheat is used (whole wheat bread also includes regular flour) and in what proportion, and what other ingredients were used to make the bread and how much of each ingredient.
White bread is wheat bread; it is made with bleached wheat flour. Many commercially produced white breads contain high amounts of sugar and artificial preservatives that make it slower to mold than natural whole grain bread.
It has to do with the way your body breaks down sugars. White bread has simple sugars, which are empty calories. Wheat bread has more complex sugars, and provide more energy. Also, wheat bread has more fiber.

If in your experiment, whole wheat bread has molded faster than other breads, you should look at the ingredients used to make the bread and the processing conditions where the bread was produced. The wheat bread could have been exposed to more mold to begin with or the other breads may have used mold inhibitors.
If you are asking what types of breads there are, then there are many different types, shapes, and sizes. Then there are the different countries that make bread differently. The most common kinds of bread are: rye, wheat, white, whole meal or whole wheat bead, mixed grain, sourdough, bagel, and gluetin free bread.
It could. That would depend upon the mold and your sensitivities.
