How to structurally decompose different Dockerfiles for the same project?

Question

PHP

I'm learning docker and want to make my first project on it.
As I understand it, each service should be in a separate container.
For example:
1. mysql
2. php-apache
3. redis
4. rabbitmq
5. data-storage

the result is 5 images that need to be built, because 5 Dockerfiles.

How structurally should they be properly organized? Really in a root of the project there should be 5 Dockerfile'of?

It seems to me that at the root of the project there should be only docker-composer.yaml which will already build and raise images from these Dockerfiles.

The Dockerfile is needed only if the main image needs to be modified, so it is enough to specify the name of the main image in docker-compose.yml and set a couple of settings if they are initially supported (username, password, etc.). For example, I usually only need to register the php-fpm Dockerfile and sometimes for mysql, I put the rest of the images as they are
