Hmm, after that next set of pictures, you should also consider Brooklynella.
That head-on clownfish picture in particular looks like it has a fair bit of extra mucus/slime.
But I simply don't know which it is.
And unfortunately, treatments are different.
IMO: Get them out, do a freshwater dip, and put in QT.
That should help a bit with either disease.
Hopefully someone else can tell.
