The first pic is minor seepage from the valve cover gasket. If it keeps going like that then the gasket should be replaced. The second and third pics indicate more of a spill from the filler cap area. Either a spill from filling or a cap not sealing well, most likely a spill. The 2x2 area on the ground, inches or feet?

That much oil (in or ft) indicate a fairly good spill. Could it be from another car? Have you had a look see under the car to see if you can see any oil there?
