Unfortunately there are a few things off the bat that I see could be changed and need to be ASAP.
There is no way you will be able to keep up with watering them and the necessary humidity in a cardboard box.
You should also separate them. If the male is napping that is not a good sign. He also has quite a bit of swelling around the neck area. I do not suspect him to do well if the female is climbing on him etc.
As a quick fix you could go get a few cheap plastic bins. Around 9 quarts should do. Humidity really needs to be high for these babies and this will help until another setup is made.
They should eat fruit flies and 1/8 crickets at the moment. After they get a little more size they should be able to eat house flies also. You can find flies at mantisplace.com but I do not get fruit flies from them just other species. Reptisun 5.0 UVB light (the linear kind) is recommended.
Unfortunately I can not add a lot more. I have experience raising other montane species but not these and the animals you got are not an easy species by far.
Here is a link for you. Kent is also a member on the forum. Hopefully he or someone else can chime in and give you more details.
