Looks like you set the camera on an automatic program, but the camera doesn't really always know what you intend. The automatic mode gives correct exposure, but not necessarily appropriate exposure. In this case it's tending towards very slow shutter speeds, resulting in images that have some motion blur in them.
The last one is out of focus, which may be a result of giving the shutter a half-press (which does all the metering and gets the camera ready, and locks the computed settings) and then moving a little bit away from the subject before pressing it the rest of the way. With the button half-pressed, the camera probably makes no more adjustments to correct for focus or exposure, which is intentional. You may want to focus or expose for something not actually centered in the frame. You point the camera at it, half-press, then move to your actaul composition, press the rest of the way and click. If you move unintentionally, though, what you had is not what you get.
Practice, and use the review on the screen to see how the image looks. You can zoom on the image to check its sharpness. An image that looks pretty good on a 2-inch display may actually be pretty nasty full size.
So learn what you want to override as you shoot. Auto is fine for family stuff around the house, usually, but when you have something specific in mind, you may want to emphasize stopped motion or depth of field rather than let the camera decide. Then you''ll want to know whether to use shutter speed or aperture as your deciding factor in setting the camera's modes.
