Any chance that they are still alive? I have no idea what they are.
I'm guessing that I should at least cook it for a day in a 5gal bucket and see how much ammonia/nite's show up and if it's 0 change the water and give it another day? I threw a powerhead and a cheap-o homedepot CF over the 5g bucket for light.

As far as actually being out of water, healthy reeftop Acroporid/Pocilliporids do it twice a day with full direct sunlight for several hours at low tides in their natural habitat, but this is usually a limiting factor for some corals depending on species.
Regarding the issue of no light for a week, many corals have already experienced this when brought to a LFS, and unfortunately low light is almost as bad as high temps and high intensity lighting about causing bleacing in the stony reef top corals. You just need to slowly acclimitize the corals to good water, good salinity, good hermatypics, current and lighting and hope for the best. Slow acclimitization wil usually bring most stony coralis back around within a few weeks, depending on what kind of shape they were in prior to whatever caused the issue to occur.
The low of 67
oF temporarily should not be an issue.
Good luck.
