Yes, you can. However, it will make the dish very rich, and you may want to change it a bit. To have a more 'normal' cornbread, try adding 2/3 half and half and 1/3 water (equalling the same amount of milk the recipe asks for.) If you think it is too watery or too rich, you can change the proportion appropiately.
Heavy cream could be used for milk in cornbread, but the baked cornbread might be heavy and too dense, because of the high fat content of heavy cream. It would be better to thin the heavy cream with water to bring it closer to the consistency of milk before using it in cornbread.

Yes, it depends on what you're making, however because buttermilk is acidic it is generally used in recipes to control the leavening/rising process. A straight substitute of milk is less acidic and will result in overly fluffy pancakes, etc... You can sour regular milk by adding 1 T lemon juice to 1 c milk and let stand for about 5 minutes. You can also substitute plain yogurt. It depends on what you're making but, for baking, buttermilk can generally be subsituted for whole milk.
