You have extra repositories where apt looks for software updates. These are listed In your /etc/apt/sources.list file. The warnings shown say that those repositories don't sign their software with gpg keys, which means you cannot be absolutely certain that you are downloading them from a trusted source.
You can just ignore these errors if you have some non-ubuntu software packages installed, and want to use apt to install any updates to them. Otherwise, edit sources.list (as root) and remove them (or comment it out with a #).
