I am assuming that they are eating and drinking, peeing and pooping, right? Are their stools runny or soft ... or are they little Tootsie rolls? Save one (even if it's runny) and stick it in a ziploc baggie (in the fridge) and take it in to your vet and ask for a fecal sample. There are LOTS of parasites out there, and lots of meds for parasites, and you want to make sure you're treating with the correct medication.
Something else this COULD be ... some cats seem to get what's sometimes called Limpy Kitten Syndrome (not the precise medical term) where their joints get inflamed and they don't move much because everything's sore ... some vets think this could be a temporary side effect from the Calici virus, or even the vaccine for the Calici virus. I'm not a vet and haven't seen your kittens, but it's something to consider.
Did you get med records with your kittens? Have they had one, two, or three vaccines? You'll want to know so you can discuss with your vet to see if another one will be needed. This will be something to ask at your vet appointment.
They may just be freaked out and scared and under-socialized. There's a 2-fold remedy for this: turkey baby food on a spoon, and a feather-on-a-stick. Basically, put some plain turkey baby food on a spoon and just sit quietly... eventually they will come up to eat some. This helps them realize you're the FOOD person! The feather-on-a-stick is, well, just plain fun!

Their poops look good. One had an accident with very runny poop, but that was in the first few hours they were in the house. Since then they’ve been perfect about using the box, and they cover up the waste and everything.
I sure hope I got the records, I have to check. They got some shots I know that.
Last night they were actually exploring around a little bit, so we were happy to see that.
One of them eats everything you offer her. The other seems uninterested in human food, but they are eating the cat food like little champs.
