      sour cream has special bacteria in it that makes it sour, but if you left it open in the air in a warm place other bacteria would start to grow and these would be dangerous to you and could give you food poisoning. The same goes for yoghurt too, but cheese can be kept open longer as it is a solid and doesn’t have the water needed for the bacteria to grown in it

      yes. Like all food stuffs, it will go off/mouldy. This will happen quicker if kept in the wrong conditions. If you make your own yoghurt at home, the original product can be quite bitter, but if you then strain the whey (the watery bit) from the yoghurt, it will get less bitter. But the sour part of sour cream isn’t because it has gone bad.
