MCV level 78.3 MCH level 25.1 Can I take Iron pills and B12 Together? If so will twice a day be fine?

Yes to both. It would be better to take iron with food to avoid stomach irritation. It does not matter for B12. You may wish to substitute a multivitamin for B12 once a day. For good health - Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form. Practice safe sex.
