Only the Active Camera will render. If you have more than one Camera in a timeline, the top Camera will be the Active Camera. The only purpose of the other views (Left, Right, Top, Bottom, Front Back, and Custom 1, 2, and 3) is to help you align layers on AE's 3D stage.
If you need to reposition everything you have two options. Move the camera or parent all of the layers to a 3D null and move the null.
Perspective is controlled by camera position, framing by focal length. The focal length in an AE camera is the Zoom value. You can find it by pressing 'aa' with the camera layer selected or by double-clicking the Camera layer.
One more thing. Cropped screenshots that do not show the modified properties of the layers giving you problems are useless for diagnosing problems. When you have problems in the future, select the problem layer or layers, press 'uu', and take a screenshot. Show us the whole UI and if possible, have the Comp selected in the Project panel so we can also see the comp properties.
