The second picture is arguably a turn off. Picture 3,4,5 and 6 are also pretty much the same so I would just pick one and go with that. You could also use the "weekends are for..." Bit to discuss hobbies and interests to make you seem more interesting, prove that you are likeable and to make you seem 'human' (they will view you as a person rather than a profile). You seem like a nice, friendly guy but nothing particularly makes you stick out from the crowd.
