Bugs of the Back Yard

I spent some time in the back yard today taking pictures, and needless to say, being in Central Florida there is an abundance of bugs. Some are good for the garden, some I am not sure of, and some could be bad. Most of these bugs were found on my Kentucky Wonder Green Beans and my Naval Orange tree. I am not sure what the top bugs or the one bellow them on the left are. There are hundreds of them and they just morphed from one form to another. There are tons of empty exoskeletons stuck to leaves. Here are 12 pictures! Well, just thought I would post the pictures. Maybe somebody can help ID the unknown bug?
