The little panfish are sunfish and the bigger dark ones could be crappies. The fish with the turquoise markings we always called sunnies anyway. They often have a yellow/orange belly. Crappies can actually get to a decent size and are good to eat and the sunfish are really tasty fileted out and fried but it takes a lot of them for a decent meal.
The way to tell between a smallmouth and a largemouth bass is that when the mouth is closed, the back corner of the mouth on a largemouth extends back past a vertical line drawn through the eye.
