The phal looks fine, don't forget to let it dry a little before watering it. over watering kills more plants than just about anything else. The Dens look fine to me, you can trim back the bloom spike on the one on the right back closer to the plant so they don't get stuck on things and tiped over. The yellowing leaves on the Dens look to be normal leaf loss after burning or even time. I have a couple of dens with older canes which don't have any leaves. sorta like really old humans have no hair... Other than that welcome to the adiction.
