Here is a closeup of the badge or label on the metal louvers in the ceiling that sit below the fan. I believe the following text is on the badge:
TYPE S60SFL-2996
CAT NO. 130CS-3

Photo of Fan Taken in the Attic:

As I type this, my girlfriend has this fan going full blast (Hi Speed). It is squeaking to high heaven! I have been up in the attic four times to attempt to address the problems we are experiencing with the attic fan.

The fan belt broke. 

The larger wheel or pulley makes a large amount of squeaking noise when I move the belt by hand. I notice some squeak, but very little, coming from the motor's shaft.

Attempts to Resolve Above Problems:

My girlfriend went to the auto parts store and I went up in the attic with what we thought was the same size belt. Unfortunately, it was not. So, we were sold another belt. After doing some reading, it appears I need some other sort of belt. A "fractional horsepower" belt. So, I guess that needs to be addressed. 

Where do I get such a belt?

I placed some liberal amount oil on top of the large pulley's shaft. This did nothing to quiet the fan.

Link to Lubricant I Used:
LA-CO Precision Spout Oiler

With the above in mind, I would love for some help to get this fan quieted down so we can enjoy this cool weather, as well as get my sanity back from listening to this non-stop squeak.

As you probably are aware, getting up and down into an attic can be a chore when you don't have attic stairs.

If anyone is located in the Saint Louis, MO area and may be able to assist, let's talk!

Turn the fan off until you get a proper belt. A automotive belt WILL burn the motor out very quickly.

You need to go to a hardware store to find a fractional horsepower belt and the belt needs about 1" of play in it. It should almost look like it is slipping when the fan starts up.

But again, DO NOT run it until the proper belt is sourced. The size is likely stenciled somewhere on the frame.

Andrew is spot on! O'Reilley Auto Parts in my area carry or can get me fractional horsepower belts. Ace Hardware carries a large selection as well.

Are there grease or oil fittings on the shaft?
You might be able to spray some oil into the lower bearing from below, up through the louvers past the blade. 
If that doesn’t work, I would remove the belt, and feel if the bearings have a lot of wear. Then remove the blade from the shaft, and pull the large pulley and shaft out the top. Then, get some oil or grease into the bearings. The weight of the blade is supported someplace, maybe the bottom of the large pulley. Make sure this thrust surface is clean and greased. 

Does the motor squeak with the belt off? Drip some oil into the motor shaft. 

Don’t overtigjten the belt.

Tractor Supply Co also has fractional HP belts if there’s one in your area
