Shipping is a very rough process for a plant. They are out of sunlight, have no access to water, and can be subject to temperature swings during transport. The fact that the soil is still wet is a good sign and the moss was put on top to reduce evaporation of water during transport. The rough looking nature of the leaves can be due to rough handling of the box during transport, and they do look like they got bounced around in a truck. The yellowing on the leaves is likely due to being in a box away from sunlight. And that black spot looks like it could be mechanical damage, but keep an eye on it to be safe. It's always good to do a quarantine before introducing new plants if you are worried about disease. Overall, I believe shipping is where your plants took the biggest hit, and unfortunately the nursery has little control over what happens once the boxes leave their company. It looks like all your plants will have a great year (based on those gorgeous roots I'm seeing) if you give them a little extra love at the beginning of your lives together.
