I'd say NamesBid sounds the best out of all them, but only if you plan to develop it into a domain auction site or something. These are brandables that don't have much reseller or end user value, I'm afraid.
The others don't really make sense, and I think they all have a value of $0 unless developed.
Almost words do not work, just because it has an (s) or is missing one (s), next to the correctly spelled top tier domain, will not give it the value you think, you are most likely in the $10-$25 range with your domains.
