I have used some of the meds you list with no issues. Others are not my brand/med of choice. Of those you list, the one about which I would be most concerned is the last one which contains Malachite Green, Methylene Blue, Acriflavine.
I do use Malachite Green but with Formalin, in the form of Quick Cure for Ich. These are still the best meds for this as far as I can tell. ProForm C also contains these ingredients.
I have never used Acriflavine, but most of what I have read seems to indicate it can cause problems, including sterilization.
A number of years ago I needed to treat ich. I was worried about the effects on the fish of M G and Form. I asked some very experienced fish keepers about this and this is what I was told. They asked which I thought was worse, treating them briefly with something that was known to work but was harsh, or allowing the ich to progress by using something for even longer and which might not work. So I use Quick Cure following bottle/site the directions for use:
Add 2 drops per gallon daily (do not discontinue filtration) for all fish except those in the tetra group.
FOR TETRAS: Add 1 drop per gallon daily.
FOR MARINE FISH: Add 2 drops per gallon daily in a bare aquarium.
Replace carbon 24 hours after last treatment. Maximum dosage: 3 daily treatments. If further medication is required, perform a 25% water change before administering another treatment cycle. Water will turn blue during treatment. This is a temporary condition and will disappear in a few days. Change 50% of water if fish show any signs of distress during treatment or an accidental overdose of this product occurs.
Can discolor silicone in glass aquariums.
