Can we define multiple workflow rules

GitLab CI/CD

I am creating a pipeline with two request parameters.
Sample script as given below

stages:          # List of stages for jobs, and their order of execution
   - download
   - execute
variables:
  # Input variables
  BRANCH_REFERENCE:
    value: ""
    description: "This variable will hold value for Branch Reference"
  RELEASE_TYPE:
    value: ""
    description: "Release Type"  
  RUNNER_TAG: "wave"
  TEST_VAR: "TEST"

workflow:
  rules:
    - if: $BRANCH_REFERENCE == "dev"
      variables:
        RUNNER_TAG: "wave-dev"
      when: always
    - if: $BRANCH_REFERENCE == "prd"
      variables:
        RUNNER_TAG: "wave-prd"  
    - if: $RELEASE_TYPE == "pplus"
      variables:
        TEST_VAR: "product_plus.tar.gz"
      when: always
    - if: $RELEASE_TYPE == "pmod"
      variables:
        TEST_VAR: "product.tar.gz"
      when: always  
    - when: always

download-job:   
  stage: download    
  script:
    - echo "Download Stage Starts"
    - echo ${TEST_VAR}
    - echo ${RUNNER_TAG}
    - echo "Download Stage Ends"
    
  tags:
    - $RUNNER_TAG
execute-job:   
  stage: execute    
  script:
    - echo "Execute Stage Starts"
    - echo ${TEST_VAR}
    - echo ${RUNNER_TAG}
    - echo "Execute Stage Ends"
    
  tags:
    - $RUNNER_TAG

Based on the input parameters I have to set some variable values. For that I have tried to use workflow rules but it is not working as per my requirement.
e.g. Below are the input parameters
BRANCH_REFERENCE = dev
RELEASE_TYPE= pplus
so for this case the value of the RUNNER_TAG should set to “wave-dev” and TEST_VAR to “product_plus.tar.gz”.

But it is working as, if first condition satisfied then rest of the if conditions get failed.

So, is it possible to use Workflow rules for such scenarios ? If no, then is there any another way to achieve this ?

Thanks.
