I am looking to script a way to get an output that tells me how many instances I have running (not stopped) in PCF. I understand that there is a way to show how many instances there are through a concourse pipeline, but I want to know how many of them are actually running. Any help would be great! Thanks.

You can use the Cloud Foundry's cloud controller API to list your applications with their states. Then it's a simple script to count how many are running.
You can query the API via this endpoint: http://api.run.pivotal.io/v2/apps
You will need an API token; a simple way is to invoke cf oauth-token from an authenticated prompt.
An example of invoking the API using curl and unix tools to count applications that are started:
curl -k -i --raw "http://api.run.pivotal.io/v2/apps" -H "Host: api.run.pivotal.io" -H "Authorization: bearer put_your_auth_token_here" | grep -Po '"state": "STARTED"' | cut -d: -f2 | tr -d '",' | wc -l
