First one is a D-15, which is NOT power. It's low-speed (probably serial) communication of some sort. The plugs themselves are readily available at electronics stores but I've no idea what pinout it will have. You can easily make through-cable for it though using ribbon.
The power cables are IEC. The male one is 15A, the female 10A. Again, readily available at good electronics stores - just take them your photo in a larger size and they will find you the right plugs.
