Please have a look at the following post: How to correctly link php-fpm and Nginx Docker containers?

Seems like you have to adjust your volumes in order to serve it correctly with nginx. So using - ./app1/html:/var/www/app1/html and - ./app2/html:/var/www/app2/html should work. Afterwards you should be able to access your applications on port 9002 and 9003. It might also work on port 84 already, but please check the other ports first.

I mean changing your docker-compose to look like this:

version: '3'

services:
  nginx-lb:
    build: 
      context: ./nginx
    ports:
      - "84:84"
    volumes:
      - ./nginx/nginx.conf:/etc/nginx/nginx.conf
      - ./nginx/app1-config/app1.conf:/etc/nginx/conf.d/app1.conf
      - ./nginx/app2-config/app2.conf:/etc/nginx/conf.d/app2.conf
    depends_on:
      - php-app1
      - php-app2
    networks:
      my-test-network:
#        ipv4_address: 192.168.21.2
  php-app1:
    image: php:fpm
    container_name: php-app1
    volumes:
      - ./app1/html:/var/www/app1/html
    ports:
      - "9002:9000"
    networks:
      my-test-network:
#       ipv4_address: 192.168.21.3
  php-app2:
    image: php:fpm
    container_name: php-app2
    volumes:
      - ./app2/html:/var/www/app2/html
    ports:
      - "9003:9000"
    networks:
      my-test-network:
#        ipv4_address: 192.168.21.4
networks:
  my-test-network:
    driver: bridge
#    ipam:
#      config:
#       - subnet: 192.168.21.0/24
