We just replaced the seized alternator and put on a new OEM belt, when we let it run after 5 seconds or so we heard a very loud squeal. Checked the tension of the belts, seemed okay, maybe a little loose. We noticed a piece of plastic rubbing against one of the pulleys and actually it being cut/melted because of the friction. We don't know what this pulley does or why this plastic is in the way. Maybe when the old belt broke it hit this and slightly moved it.

Those pics are so wide it makes it impossible in my view to see anything useful. Whatever broke with old belt has to be fixed simple as that. If that fast it must be obvious what is broken,

I have deleted your pictures until you can resize them. They make the thread impossible to even read.

Sorry, I noticed that too but then had issues trying to get imgur to re-upload... Works today though.

Pics aren't helping me anyway. Are all pulleys in a "plane" with each other? Wrong alternator pulley maybe? While belt is off spin the other items to see if they are good.
IDK - is crank pulley in line with others? All questions, sorry. Do # of grooves in pulleys match the new alternator? Was the old alternator really seized up tight and couldn't turn at all? No warning on that?
There aren't usually many surprises like this without something being obviously wrong,

Picture shows grinding against a plastic piece.
I can't remember the orientation of the pulleys, a plane sounds right but I'll have to confirm when I can (car is 30 miles north of me). I don't think it's the wrong alternator pulley, belt fit nicely within the grooves and it spun freely and fit nicely. Good that you mentioned spinning the other pulleys, the one in question which is presumed to be grinding wasn't as smooth to rotate as the new alternator pulley. In fact it had a slight tick noise to it and a tactile feel - definitely wasn't 100% free unless that's how this pulley's supposed to work.
We aren't sure which pulley this is, lowest one on the engine.
Old alternator was completely seized.

Must all be in line/plane or couldn't rub! That or the item I can't see moved somehow into the way?
I don't have the belt routing diagram real handy but think I can find it later. AutoZone's site may show it if not still on a sticker underhood - most are.
This has to look good right away with new belt driven parts and belt or don't even try to start it. Crank pulley may have slipped out or another but you should see that easily by eye if putting the belt on correctly it would stand out like a sore thumb,

I've highlighted the area I'm referring too.
I'll look for a diagram when I can, only so much work I can do at work when it's not work's work ;)
We've had it running, and it's fine for the first 5 seconds or so, then the squeal and some black dust emits. The alternator belt is warm compared to the serpentine belt.
If this is the crank pulley causing the issue, any idea what this plastic right next to it would be?

That looks like the water pump is digging in to the timing cover. Something is coming apart in either the water pump or the timing belt.
PS,your pictures are still too big except for the one with the square box..

Thanks for the information, I'll pass that along and see what we learn from there.
Pictures noted.
I'll keep this updated.

I shouldn't do this but this is what things should look like if the 1.6 (most popular engine) from the Autozone parts site.
Shows belt routing sticker in one of the pics too..........

If not that engine choose the other if only for pics of your set up as it should be,
