Will an orthodontist or oral surgeon be able to correct my malocclusion 2 even though i have 8 veneers on uppers?

Possible: It is possible. Your question really requires a consultation with a dentist who has advanced training in occlusion and experience with complex orthodontic cases. In my office i would bring together 3 dentists to work together on a case like this. Our orthodontist and i would be the most likely team to resolve this issue.

Yes: The orthodontist will have to be careful but he should be able to correct your malocclusion.

Probably: Don't know what your malocclusion looks like, but veneers can be bonded to with brackets, and not a problem for the surgeon.

Yes: Braces are attached to the crowns of the teeth but its the roots that move within the bone.

Yes: Ultimately you may need them redone if they chip or break during treatment.

Yes: One option to consider is invisalign. Some class 2 occlusions can be corrected without attaching anything to the front teeth. Especially important if they are veneered. Consult with your dentist and express your concerns.

Yes, but...: If veneers changed the shape of the teeth they may have to be reshaped or replaced. It is best to do orthodontic rx before doing restorative rx, thus putting teeth in the best order in which to be restored (veneered). Often ortho rx eliminates or reduces need for restorations. Consult with a qualified orthodontic specialist who will, in turn, contact your restorative dentist to work out best rx.
