In the future, Liquinox Vitamin B1 is great for stressed plants. It's acidic as fuck so make sure to pH it before watering.
Your crispy leaves won't heal themselves, but may stop dying back. After a week or 2 your plant should be over it.
Great, good luck. I'm also a major fan of Liquinox Vitamin B1 for transplanting. Zero shock and super happy plants.
Put some VIT B 1 down, helps with transplant shock.

From what I can tell, yes. The EXACT SAME thing. I was thinking that the Co-Op fucked up their pricing or something.
Edit: I checked their website. They only have the Gallon size there but it's still cheaper than Amazon. Here's Amazon: https://www.amazon.com/Liquinox-0-2-0-Start-Vitamin-1-Gallon/dp/B000OVCDU0/ref=sr_1_1?dchild=1&keywords=Liquinox+0-2-0+Start&qid=1603211493&sr=8-1 and heres the Co-Op: https://shop.grangecoop.com/products/liquinox--start-b-1-gallon-70134.html
Check out the first plant, see the topmost leaves and how they're hooked/curled under pretty aggressively? Were they like that before you transplanted? I wonder if this one is showing signs of overfeeding.
All are likely stressed from being rootbound, underfed in previous pots, and their recent transplants.
Buddy in the solo cup needs a bigger pot for sure, even if she has room to grow in the cup. Let her grow into a healthy pot-size (5-7gal ).
Plant#2 may just be experiencing transplant shock. The soil looks damp, so leave her be and let her gain her bearings and stretch her roots a bit. Overwatering right now has pretty negative effects.
Plant #3 and #4 look fine. Give everyone a break in dappled sunlight for a week while they get it together and then start up with some nutrients. Will they stay outdoors? If so MaxSea is a great product and fairly cheap (the website I linked isn't cheap, but shows the products).
To avoid transplant shock in the future, Vitamin B-1 is amazing.
For future reference, I've seen phenomenal results with Liquinox Vitamin B-1 for transplants. 1 Tbs/gallon, no signs of stress whatsoever.
Someone said to mulch, that's a great idea. I have wrapped my pots in bamboo fencing when they're outdoors in the sun. It keeps them SO MUCH cooler.
Try to transplant on a cloudy day or in the shade and leave your plant in the shade for the rest of the day.
