Are these 3 switches wired correctly?
In terms of electrical connectivity, yes, the switches appear to be wired correctly. BTW: the big nut o' white wires in the back means that power's actually fed to the switch box first instead of being fed to the light first with a switch loop to the switch.  This is a good thing because it makes installing fancy timers/smart-switches/etal much easier than in a switch loop configuration.

However, there are a couple of minor workmanship issues that I'd like to point out before the inspector does.  First off -- there is no reason to double-tap the pigtail for the left and center switches -- the center switch provides its own pigtail which can be nutted in to the nut o' black wires with a wirenut of sufficient capacity.  Second, your box has lost the clamp plate for the cable on the right -- it may be possible to hack it by transplanting the unused clamp plate from the left top to the right top, though.  (Of course, you can always clamp the NM as if it were a standard metal box provided box fill allows for that...)
