If you don't repot them any soon again and don't overwater, they'll be fine.
Orchids are epiphytes and don't depend on the medium as much as other plants do. I know people who grow phals on rocks, bare root or in pure sphagnum moss. Any of these options would kill my orchids very soon, so I stick to pure bark medium and double pots (the inner pots are with ventilation holes), so I can control the humidity level depending on the temperature / humidity outside by taking them out of the outer pots or keeping them in double pots. This seems to be working in my conditions.
Phals can grow in anything as long as you are able to maintain some basic conditions for them. So you have to find smth which suits both you and your plants.
Actually I made the same mistake last year - couldn't stop repotting my orchids, as every time smth seemed to be wrong either with pots or with medium, with roots etc. It resulted in multiple otchid deaths.
The worst thing is to repot them endlessly when they are growing new roots, each time you are disturbing them, the roots would "freeze" and then when you finally think the orchid is perfectly potted, the growth period is over and all you can do - wait till the next one (here it's usually around spring), IF the orchid is able to survive till then with the roots it currently has. 80% of mine didn't make it tilll spring.
So I would suggest you don't repot them anymore, just water moderately and be patient. And if they are healthy enough to survive, sooner or later they'll give you a sign.
Hope it all works out fine
