Solution 1

With the ID or Text property of HyperLink you can come to know which HyperLink is clicked actually. Try this:

C#

HyperLink hl = new HyperLink();
hl.ID = "HyperLnk1";
hl.Text = "HyperLnkText1";
PlaceHolder1.Controls.Add(hl);

hl = new HyperLink();
hl.ID = "HyperLnk2";
hl.Text = "HyperLnkText2";
PlaceHolder1.Controls.Add(hl);

Now you can recognize the hyperlinks using Text or ID property.

Any event, where ever you are trying to find the clicked hyperlink name. Find your control first and compare it.
If you are trying to find it in next page, then:
HyperLink hl=(HyperLink)Page.PreviousPage.FindControl("HyperLnk1");

If you want to subscribe to a click event I would rather use the ASP LinkButton control than a regular hyperlink. Example:

protected void Page_Load(object sender, EventArgs e)
{
    LinkButton linkButton = new LinkButton();
    linkButton.Text       = "LinkButton";
    linkButton.Click     += new EventHandler(linkButton_Click);

    PlaceHolder1.Controls.Add(linkButton);
}

void linkButton_Click(object sender, EventArgs e)
{
    LinkButton linkButton = sender as LinkButton;

    if (linkButton.Text == "LinkButton")
    {
        // Open a different page
        Response.Redirect("WebForm2.aspx");
    }
}
