Answer 1

You could try

public async Task SendMessage(string user, string message)
{
    await Clients.Others.SendAsync("ReceiveMessage", user, message);
}

I tried with the codes in this document,just modified the codes in hub

And the result:

Send message to specific user you could check this document.

Update

I add the codes in chat.js:

document.getElementById("sendButton1").addEventListener("click", function (event) {
    var user = document.getElementById("userInput").value;
    var message = document.getElementById("messageInput").value;
    connection.invoke("SendMessage1", user, message).catch(function (err) {
        return console.error(err.toString());
    });
    event.preventDefault();
});

Add another button in page:

<div class="col-6">
    <input type="button" id="sendButton1" value="Send Message" />
</div>

Add this code in Hub:

public async Task SendMessage1(string user, string message)
{
    var a = Context.UserIdentifier;
    await Clients.All.SendAsync("ReceiveMessage", user, message);
}

Result:
