Hi and welcome to the forum

It's bruising/ fat lip from swimming into things. This is common on new fish when they go from a bigger tank into a smaller one or a tank that is a different size and has really clean glass. They often swim into things and because they have soft mouths, they damage their lips easily.

Keep the tank clean (big regular water changes & gravel cleaning, filter cleaning) and add some salt to prevent secondary infection. see directions below for info on salt.

The blue ram has excess mucous under its jaw. The fish probably injured itself and is producing mucous to protect the injury. It should clear up by itself over a few days if the tank is clean. You can do a big water change and gravel clean to help speed things up.

Rainbowfish need lots of plant matter in their diet and at least 50% of their diet should be plant based. Try to have some live aquatic plants in the tank for them to eat. Duckweed is a small floating plant that most rainbowfish love to eat.

SALT
You can add rock salt (often sold as aquarium salt), swimming pool salt, or any non iodised salt (sodium chloride) to the aquarium at the dose rate of 1 heaped tablespoon per 20 litres of water.

Keep the salt level like this for 1-2 weeks.

The salt will not affect the beneficial filter bacteria, fish, plants, shrimp or snails.

After you use salt and the fish have recovered, you do a 10% water change each day for a week using only fresh water that has been dechlorinated. Then do a 20% water change each day for a week. Then you can do bigger water changes after that. This dilutes the salt out of the tank slowly so it doesn't harm the fish.

If you do water changes while using salt, you need to treat the new water with salt before adding it to the tank. This will keep the salt level stable in the tank and minimise stress on the fish.

When you first add salt, add the salt to a small bucket of tank water and dissolve the salt. Then slowly pour the salt water into the tank near the filter outlet. Add the salt over a couple of minutes.

How big is your tank and how many of what fish is in it?

In some of the pictures of the rainbow fish it looks like they are almost peeling. I am not sure what that is but just figured I would point it out to people who have more experience. The dwarf gourami could be getting bullied by someone in the tank or could have gotten scratched on something in the tank. He does kind of look a little bloated. Have you tested for ammonia, nitrites, etc?
