Which nose surgery should I do?

If your only concern is frontal view then alarplasty and tip refinement is satisfactory however raising the bridge of your nose may be a good procedure to consider but I cannot comment on degree of augmentation without seeing profile pictures.  With your somewhat thicker skin type and typically weak tip cartilages, improved tip definition is best achieved with addition of one or several layers of cartilage.  I do not recommend silastic L shaped implants to improve tip definition.  In my opinion this appears artificial and I have seen many patients over the years who require implant removal on account of infection.
