I actually like 1 & 2 the best; I see 3, 4 and 5 as having topline issues, and 6 looks generally unhealthy. Since 2 is only a kid, his current conformation might be unreliable, so I would be sure to get pictures of his dam and sire before making any decisions. I really like your idea of crossing with Kiko! Hope it works out well for you

I would say that at 3 months of age, they start to develop and reveal their 'forever' qualities, but at 4-5 months is when you will see a smaller version of what they will look like in adulthood.
