I can see a queen cup in the second photo, I wouldn’t be concerned about that one. It wouldn’t warrant me looking inside it. However I’d look inside the two, possibly three queen cups in the 3rd photo because they are made with fresh wax & extended down a bit. They might be fresh queen cups, which bees build all the time, while they have no intention of swarming at that time.
To give a simple answer: if I have any concerns about extended queen cups, I always look in for eggs, larvae or even a wet substance that I think bees place in there to encourage the queen to lay.
