Well If your planning on doing acros I'd probably leave 2 and 6 and open for that (depending on how many varieties you wants). 5 Would be a good place for the favia or the encrusting montipora because it looks like its separate from the main rock work so the encrusting corals couldn't completely take over the rock work. Favia have a wicked sting and stupid long sweepers so its important to give them a lot of space. You could put a torch at 8 if you wanted to have most of your euphyllia in one space (although I'd move the duncan because torches don't play nice with others, not even with hammers or frogspawn) or you could add it to the 1 area if you wanted to spread the movement these coral provide more evenly around the tank. The acans could be kept on or near the sandbed to free up a little more space as well. I think the issue with helping you do this and perhaps what deterred others (although possible your thread just got lost in the sea of new post) is that it kind of comes down to personal preference and what your vision of the tank looks like once its all grown in.
Outside of the flow, light, coral warfare, ease of access for feeding etc considerations it really comes down to your preferences.
Something that has helped me figure out coral placement in my tank is doing what you did above but placing color/shape representations of the corals in different places. This well let you find what colour combinations you find most attractive, give you a sense of how these corals might fill out and best of all you can see "that spot might be too close to the favia" instead of finding a zapped coral there the next day. Heres an example of the one I made for my tank, I hope this helps!
