Retrieving secrets

If I have a secret in secrets manager with 5 secrets in, but I only want to retrieve 2 specific secrets at a time for my application is there a way I can do that? Also, when retrieving how would I only get it to output the value? For example. If I have secrets A = XXXX and secret B=YYYY combined under secret 1. How do I retrieve just A from secret 1 and, showing only the value of XXXX instead of A=XXXX?
