You can't, there is only a single subject DN in an X.509 certificate.

That's exactly what SANs are for and why you an use --san multiple times.

The server uses the trust chain to verify that the client certificate is
issued by a trusted CA certificate and checks the signature in the AUTH
payload that proves the client is in possession of the private key. The
DN and SANs are used as identification of the clients (and you could
e.g. match them in different configs).

Then you obviously haven't added the connection configs to the right
file. Did you add them to /etc/strongswan/swanctl/swanctl.conf?
