DefenceExpert.com might fetch $XXX
Not much love for the second domain.
I'm not a fan of .org as it is often viewed as charity sites (who ain't gonna pay shnizzle for a domain) but Summarise.org has some value in my opinion perhaps ($XXX maybe even $XXXX for a right end user) but be warned it will be a wait of possibly 5 years.
Might get a couple of hundred for the 4th (again don't like .org extension)
In the .com I would be a big fan of the 5th domain and for that reason even the .org should have some value however a company is far more likely to splash out a little extra cash for the .com than go for a worse deal with the .org
