A few things to help you on your domain journey:
Non .com/.net extensions need to be very strong word combos, and highly popular in search engine results. I don't see alot of results for the non-coms you have. Use "word1 word2" in quotes in google for SERPs.
As for those that have TMs in them, we can't appriase those on this forum.
FreeFlutter is probably your best, simply because it is direct and simple and easy to remember.
However nothing posted has a resale value to domainers. You would have to try to find End Users to buy these which can be difficult.
