Some of them aren't terrible
Raisecash.org is ok, but maybe a bit scammy sounding
Careermove.org is not bad and works well with org
Collegecourse.org is probably the best, plus suits the org extension.
I'd probably focus on these. Stick them on a popular market and price to sell. The last two I'd probably renew and give them some more time if needed.
Personally I wouldn't waste my time with the others.
