I'm going to reply to just the one thread...
all the corals you posted are all basically harmless. The first pic in the first thread, I believe those are just harmless yellow polyps with some zoas all the rest are harmless to you.
The hammer coral does send out some sweepers looking for food and can/will sting other corals that are close to it with the exception of most other euphylias (hammer, frogspawn, torch corals)

I wouldn't suggest eating any of them, but you have nothing to worry about from just incidental contact with any of them. Wash hands before they go in to the tank and wash them again when you are finished.
As I stated in your very first post, I can see nothing at all that I would call a palythoa sp. You do have some zoanthids and yellow colonial polyps that have the ability to spread in the right conditions, but otherwise what I see is a good selection of some of the easier LPS corals.
You either are allergic to the palytoxin or you aren't. IF you are they should be avoided. I have handled palys many times long before this was a well documented thing and rarely washed my hands after handling and never had a issue. Everyone is different
You dont need to be allergic to palytoxin to get poisoned by it, and I am not sure if you can even be allergic to it as palytoxin is not a protein based compound. Its just toxic compound, if enough gets in your blood stream, it will stop your heart regardless of allergies or anything else.
The thing is, it is not easy to get it into blood. Palys do not excrete palytoxin and it is not a volatile compound that vaporizes easily. The only way of getting is by destroying a paly and releasing the palytoxin in their tissues, and then somehow getting exposed to it or worse boiling rocks that have palys on them and forcibly vaporization and inhaling it. It sure is a dangerous compound, but it is not something that, out of nothing, can kill you.
Learn something new everyday, guess I have been lucky in the past. I would never boil rock so that didn’t ever cross my mind and I’m sure that would wreak real havoc on the inhabitants of the house
