Export-grade cipher suite:
Export ciphers used to be legally exportable from the United States of America in the 1990s, when exporting military technology was heavily restricted. Nowadays, they are considered insecure (cf. FREAK Attack).
Rivest Cipher 4:
IETF has officially prohibited RC4 for use in TLS in RFC 7465. Therefore, it can be considered insecure.
Message Digest 5:
The Message Digest 5 algorithm suffers form multiple vulnerabilities and is considered insecure.
