pinoyteens.net - maybe you get your registration fees back ;-) Just to make it short.

randomposts.net - sounds more interesting. Could be used for a marketing related service, maybe e-mail or permission marketing. Maybe also a discussion board as well. Also the .net TLD fits here. I would rate it around $1.000 USD.

badits.net - same as first, no dictionary words.

uniboards.net - this is my favorite in your collection. Could be used for some community projects, discussion boards of various topics. I would rate it around $2.000 USD and more (at least I would develop an own business unless you can sell it for this amount).

kevinpaquet.com - maybe worth thousands for Mr. Paquet, but not for anybody else ;-) Maybe his fan club (sorry, I don't know him, is it an actor, songwriter, Internet guru ?)
