Of them all I like #4 the best, but with slight modifications. I like the icon of the dove clutching the leaf. However, I would inverse its position and move that icon to the left, and have the dove face the other way.
Logo #2 is good because it incorporates the charter oak, the official Connecticut state tree. However, the CT government probably uses that logo on everything so it might not be the best option. It's a nice, classy looking logo though.
Logo #5 puzzles me. A big problem with it is that the arrows point up. I would have figured you'd want the arrows pointing down seeing as how the business helps people bring their debt down or down to manageable levels. I'm also not a fan of the orange arrow in the middle either.
Overall, I'd rank them like this, from best to least best: 4, 2, 3, 5, 7, 1, 6
