Hi MMG, welcome to the forum and to domaining.
There are many such names, and better, still avail to reg. That being said, I still find many of these kinds that get enough searches to pay their reg fee or a few times that, each year.
I think with your names, it'll depend on how much the traffic brings you. Just looking at them, and their Overture, right now I'd appraise at reg fee or only a little higher.
But I wanted to comment that you're headed in a good direction - so many beginners that can't afford to buy good existing names just reg 'inventive' names, thinking that others will love them the moment they see them; but selling names like that is a rarity, and you're doing much better by only regging a few of those kinds, and trying to build up a solid portfolio of small traffic names like this kind you've posted here.
With internet use growing hugely each year, small traffic this year means a little larger traffic next year, and so on, and so on... and 5 years from now your beginner's portfolio of names brings you enough income to live on each month.
At least, that's the process/theory many of us are using, and succeeding, on.
There are many, many ways to make $$ thru smart domaining, and your names show that you're using your head already. Stick around and you'll pick up a lot more tips.
Care,
Ban
