Bees hang around in the front entrance of the hive

Dear BeeMasters

Finished my dinner and observed 2 of our hives in the backyard - I found several bees are hanging around in the front of the hive entrance (both hives)

[attachment=0][/attachment]
This hive was swarm captured colony - 11/10/21

This hive was from the Nuc that I transferred to 10 frames polyhive - 18/11/21

Can anybody tell me what the bees are doing - T. 22C, time 19:45 (wet summer time in Oz)

Thank you

It looks to me like they are doing just what you said, hanging out.  Now that the hives are a little bit larger and they have worker bees to spare for the job, you will commonly see guard bees stationed at the entrances to keep out any intruders.  It's also common on summer evenings for foragers to just hang out on the porch when the weather is nice.  At its most extreme, this behavior is called bearding, and it results from the adult workers moving outside to help keep the hive cool by removing their body heat from the brood nest.  I wouldn't call what your hives are doing "bearding" by any stretch, but remember that bees are cold-blooded and must regulate the temperature of the brood nest for the brood to develop properly, so you may see bees fanning or just hanging out at the entrance to help control the hive's temperature.
