I don't see any troubles there. The pup next to the super withered pachanoi will do just fine. I'd keep an eye on the withered one though. At the first sign of rot get it out of the pot and double check the roots for bugs or rot in the soil. I'd guess there's neither bugs nor rot but there's no harm in checking.
how long has the withered cut been in the soil? If it's been six months and there's no roots I'd yank it ...... and check the bottom for rot or bugs
if buggy or diseased repot the pup in new soil and get the bad soil away from your house and garden
but nothing about the soil looks off in the pic - so maybe it's just some bad luck for the original cut you tried to root. It happens occasionally.
