Dairy Queen is trademarked, so unless you hold that trademark - I would get rid of it. Don't know too much about .ng, but the CB4A.net I would imagine going for mid $XX.
CB4A.net is not a LLLL but a LLNL and in .net prob about low mid xx
TechCabal.com.ng - .com.ng would significantly lower the value, maybe developed xxx
