VegasAirfares.com is good if it gets a little traffic. If no traffic, then it still has value because you could brand it quite easily. I would put that at low XXX without traffic, and higher depending on how much traffic.
LatinMusicAwards.com seems like it is worth something, but you will have to get lucky to sell it, I think.
TenYards.com is worth zero to me.
BradyStreet.com worth zero. I used to have the name MartinStreet.com and there were even 3-4 sites with Martin Street in the name and they wouldn't even buy it for low XXX, which was amazing. I spent a lot of time trying to sell it. I learned my lesson. You would have to get very lucky.
PolkStreet.com worth zero. (see above)
iFunctions.com is a tough one. It could be worth something. I probably wouldn't reg it, though, so I'll say zero.
