If you're asking for a buttermilk substitute, place one tablespoon of lemon juice or vinegar in a one cup measure. Fill to one cup mark with regular milk and let sit for five minutes. Use for buttermilk in any [[Q/Can you replace milk for buttermilk in a recipe#|recipe]]. I don't think plain milk would give the correct flavor to the recipe.
You can most definitely use buttermilk for scalloped potatoes. It will give them a nice flavor. I suggest adding some fresh Rosemary to complement the twang of the buttermilk.
I wouldn't suggest using buttermilk in carrot soup. It would give your soup a soured flavor.

Yes, it will give it a sour taste.

The standard substution for buttermilk is to add one teaspoon lemon juice or vinegar to one cup of regular milk, which will give pretty much the same result as commercial buttermilk.

No. Buttermilk taste like yoghurt; it's more acid than milk. So using it in mac and cheese will give a fairly revolting result.
