Yes, you can. Olive oil will affect the flavor of the muffins, so would be most successful in savory muffins - corn, cheese or spicy muffins with sage and thyme, or chopped onion and celery. For sweet muffins, I recommend canola oil because it has a neutral taste. But olive oil works for sweet muffins, too. It's used in several types of Italian cakes.
If for baking, you can use sunflower oil.
Probably, but it depends on the recipe.
If you use clear or "light", or extra light olive oil then yes you can. Do Not use virgin, extra virgin or pomace oil as these will impart an undesireable taste.
