Another beekeeper here. Those don't look like queen cells, just random bits of comb with cells pointed all over because it isn't on a frame. Never seen this happen, but new swarms tend to build like crazy. I bet you can give them another box. How are they building inside? Filled out yet?
Also what region are you in? Kinda late to have a swarm. "Swarm in July ain't worth a fly" and all that, they rarely can build up in time for winter, but maybe you're in a winterless place like southern Texas. I'd guess, if they're built up inside the box you can give them another box to go upwards. Maybe put it on bottom if they seem really into building down.
