I found these animals recently and I am not even sure if they are nudies. I have been seaching for a couple of weeks with no results. Hopefully you can help me out with an id because I have absolutely no idea.

You are entitled to be puzzled by this/these animals. The tentacles do have the look of a dorid circlet of gills, but they are the feeding tentacles of a Sea Anemone. This is outside my area of expertise but it looks like a genus, Nemanthes, which is often found attached to the stalks of branched colonial animals like gorgonians, sea whips, etc. Because of where it lives, it doesn't have the normal circular attachment base, but instead a long elongate extension out each side to wrap along the stalk it is attached to.
The other interesting thing is the presence of small juveniles alongside, suggesting that this is an anemone that reproduces by budding off small clones of itself.

Once again I spent some time in the Visayas region and I'm happy because I found some sea slugs never seen before. One of them I cannot identify. Can you help me? This nudibranch I've seen on the west coast of Cebu Island (Philippines). Attached the image.
Thanks very much and kind regards from Switzerland

I think this is not a nudibranch but rather a Sea Anemone with its feeding tentacles partly retracted. One other animal that came to mind was a benthic ctenophore but I don't think so.
I'm afraid that sometimes it is a bit hard to identify an animal from a single photo, especially when they are not sitting in a 'typical' pose. I don't know of a sea anemone with this colour pattern but I cna't think what else it could be. Perhaps someone will recognise it.
