What are these

Please if anybody can ID these look good. Be good to know what they are harmful to the torch, if need to get rid of, and how?

As mentioned, my guess is bivalves - harmless filter feeders:

Are you asking about the things with shells that appear to bivalves of some kind? Because it looks to me like a couple of bivalves with the mouth/mouths (the fleshy parts) circled.

If not, you may need some clearer pics for an ID.

Bivalves. Look ideal. Will the end up harming the torch that they are growing on. Meaning stressing them out til death

No - they shouldn't cause any issues at all.

Top ones look to me to be a typical Jingle Shell. Harmless bivalve.
