Does this look like the main valve? If so, which way do I turn it to stop the water supply?

    It might be... Whether it is or isn't, if it's a quarter turn ball valve -- it will be open (as seen) when the handle is parallel to the pipe, and closed with the handle at right angles to the pipe. However, it isn't a pattern of valve and handle I'm really familiar with. Maybe someone else?

    Either that lever handled ball valve, or the more conventional valve below it, should shut off the main water service. The lever handle valve may have been installed because the other valve below it was leaking.

    The armored electrical service ground attached to the piping is the giveaway. That is done where the water service enters the building.

    it should only turn 1 way thee is usually a sop on the valve so it only turns 1 way. As others have said if the handle is 90 degrees wit the pipe it is off parallel to the pipe its on
