Parasitic such as Ick, fungal infection, bacterial infection. If the spot doesnt look like a grain of salt and is singular than it is probably not Ick.
The appearance of a white spot on a goldfish's head is typically caused by a parasitic infection known as ich, or white spot disease. This is a common condition in aquarium fish and is characterized by small white spots on the fish's body and fins. It is important to treat ich promptly to prevent further spread and potential harm to the fish.

I have an incomplete answer for this. I just got a tattoo of a koi fish that I designed (without the spot). I got it done in Japan and the tattoo artist decided to add it. He explained to me that it when a koi fish gets older...something something...and that it was very japanese. I has something to do with the aging or wisdom of a koi fish.

Treatments may include medicated baths, water changes, and adjusting the tank environment to improve water quality. Consulting a veterinarian or fish expert for a proper diagnosis and treatment plan is recommended.
With a guppy you need to look at the gravid spot. This is a dark spot in the fish's belly. A large gravid spot indicates the fish is likely to be pregnant. You can tell how pregnant the fish is by how large the spot is. Sorry I have no experience with other species.
No. Babies have a "soft spot" on their head but it eventually closes.
The gravid spot on a platy fish is a dark spot near the fish's anal fin that indicates pregnancy. It is caused by the darkening of the skin due to the developing embryos inside the female fish. By observing the size and darkness of the gravid spot, one can determine the reproductive status of the fish and whether it is pregnant or not.
A white fuzzy spot on a fish could be caused by a fungal infection.
