I find that when the pressure is low on everything it's usually a pressure regulator gone bad.
Could be that a shut off valve isn't on all the way. Have any plumbing done lately? Check the valve in the meter box as well.
Could be a filter on the line needs cleaning.
Could be all 5 valves are bad. Open one with them with the bleeder screw and see if you get more pressure.
Check the flow controls to make sure someone didn't turn them down.
