I bought two belts that go around the compressor and power steering pump and when I got home I noticed the packages have slightly different measurements. One is 13/32" x 60 1/8" and the other is 3/8" x 60 1/8". Measured in MM one 1525mm and the other is 1526mm. That small difference should be fine right? the teeth on both belts look different too.

If all your pulleys are cut for two V-belts on each accessory you MUST use the same - exact same - belts. While the same part number is OK, a few belt manufacturers package belts in matched pairs.

Take a hard look at one of my marine engines that I built - the belts are a matched pair from Gates. At least get the same top width belts - that should be easy.
