As a legal term, "hearsay" has the narrower meaning than what it means to a lay person. Use of the statement information as evidence to prove the truth of what is asserted is hearsay.
Such use of "hearsay evidence" in court is generally not allowed. This legal prohibition is called the hearsay rule.
Any out of court statement, document, audio recording, phone call, written statement is hearsay IF you intend to use that at trail for the truth of the matter asserted therein.
Definition -- "Hearsay" is a statement, other than one made by the declarant while testifying at the trial or hearing, offered in evidence to prove the truth of the matter asserted" See, Federal Rules of Evidence
So, all of what you are mentioning is hearsay and you need to uncover an applicable hearsay exception.
