The fact that you had the private key separately probably means that the multiple certificates are either in PEM (base64) or DER (binary) format. Open it up in a text editor, or 'cat' it from the command line. If you see a bunch of characters that start and end with "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----", then it's in PEM format. If there are multiple certs in the file then you'll see them clearly delimited by these "headers". You'll need to open the file in a text editor or vi and separate them into individual files. Now that you have separate certificates, you can generally open them up in Windows with the CryptoAPI utility, or from the Linux shell with OpenSSL to see what they are:
openssl x509 -in [path to cert] -noout -subject
