#12 is my favorite so far, I am curious to see some variations of the text on these logos, also on this version, the center piece is throwing it off a bit for me, perhaps try a str8 up and down line inbetween the ends of the lines. Or maybe remove the center line all together.
#9 is very cool as it looks like a pill, something like this may be great for their prescription card site.
#11 I am not sure what this is, and #10 is cool but I do not think appropriate for what they do.
Thanks for great work, I will continue to look for logos I like and add them for your reference.
