Hmmm....I agree with many here. It depends on the context for which these photos are for. You look either too serious...or too silly in most pics....so it depends on the situation.
Overall..I think your best pics are #9 or #5. More friendly look...and I think its your better side. Also...the outifit may need some altering. Definitely need to button up one more on that particular shirt for that look. Also..too much contrast between jeans and button down shirt/ jacket for daytime. You might be able to pull off that outfit at night..when the jeans hide better. But you should really wear something a little more formal or at least darker pants if you want to keep a shirt/jacket look. But again...all depends on what context these are for.
Good luck man.
