Generally speaking, the "Could not establish trust relationship for the SSL/TLS secure channel" would be an expected response if the connection only supports HTTPS connections and you're trying to use an HTTP monitor.

Use an HTTPS Monitor for those targets, and make sure that the SAM/NPM server has the required SSL/TLS certificates installed so that it can validate the SSL/TLS connection to that web target.
