Squealing noise
Sounds like one of your pulleys is bad. Alternator, water pump, don't know till you find it. You say you have more than one belt-try taking one off at a time, run engine for a couple of minutes and see if squealing goes away. Maybe you can isolate it that way.
If belts are off, you could spin each pulley by hand to see if you could catch the one that is bad. Any little wobble or play in any of the pulleys would be very suspect as the likely bad one.
Squealing
