Maybe: Fatigue has many causes. A visit with your health care provider might provide insight into the reason(s) you are fatigued. Vitamin deficiencies are not the most common causes of fatigue.

Not really: B12 deficiency may be dietary or related to gastric disease. Vitamin d is both absorbed and converted in the liver and skin to active forms. Vitamin c, e and others do not have the same absorption pathways nor the same actions. Vitamin k as an example is related to clotting, while e can help skin collagen deposition. They are all different and unique in function and action.
