Yes they can but every plane is checked by ultrasonics on a regular basis to check for stress cracks. Many aircraft are now being made with composite materials which are much stronger and lighter than metals. The composite also suffers from stress much less. The new Boeing Dreamliner will contain over 60% composite.
Major stress failiures in aircraft are now very rare as so much more is now known abou the causes and how to detect the problems before they become a danger.

Sorry, buddy, but turbulence doesn't come from metal fatuige. That is a totally different question dealing with fluid dynamics. I'm a Mechanical Engineering student and am currently enrolled in courses dealing with both matters. Stress comes from many different places. Stress in the wings comes from lift. Lift must be a force greater than the weight of the plane. with the weight of the plane pulling down and lift pulling up, this bends the wings up and creates stresses at those joints. Before any plane is allowed off the ground, stress tests are performed by holding the plane down and pushin up on the wings till failure. This gives a measurement of the maximum stress the plane can handle before failure and they can make sure that the maximum stress is many times greater than the plane can handle under normal conditions. There are other stresses involved, but i think these are the stresses you were probably thinking of.

Yes, there was a good film about this called 'No Highway' with James Stewart. All about metal fatigue in an aircraft.

Quite true. I've seem shows about air crashes and some of it was due to metal fatigue.

yes ,thats what put an end to the first jet passenger plane the BRITISH COMET after about 3 serious crashes they tested and found out about the stress,outcome was all planes now have rounded corners on windows etc, and no sharp square corners and that was in the 50/60s

YES ,after aerobatics there are regular checks made for stress fractures on fish plates and wing root joints amongst others,using a red stress fracture detection dye,which highlights the cracks if any.

Stress=Force/ Area. On the surface of the plane.

Yes it was the cause of the DC10 aeroplane crashes a few years back

yes but that is where Turbulence comes in
