Am not 100% sure on your question so this will be a wide answer.

1) Everything can be in the same compose file if it's running on the same machine or server cluster.

#proxy
haproxy:
  image: haproxy:latest
  ports:
    - 80:80


#setup 1
ubuntu_1:
  image: ubuntu
  links:
    - db_1:mysql
  ports:
    - 80

db1:
  image: ubuntu
  environment:
    MYSQL_ROOT_PASSWORD: 123


#setup 2
ubuntu_2:
   image: ubuntu
   links:
     - db_2:mysql
   ports:
    - 80

db2:
  image: ubuntu
  environment:
    MYSQL_ROOT_PASSWORD: 123

It's also possible to combine several yml files like
$docker-compose -f [File A].yml -f [File B].yml up -d

2) Every container in the build can be controlled separately with compose.
$docker-compose stop/start/build/ ubuntu_1

3) Using $docker-compose build it will only rebuild where changes have been done.

If none of above is correct please example of build.
