    You may use ViewState/Session/HiddenField to save the path of uploaded file in Click handler of button2 and button3.

    protected void Button2_Click(object sender, EventArgs e)
 {
   if (FileUpload1.HasFile)
    {
      .....
      ViewState["file1"]=Server.MapPath("~/upload/" + FileUpload1.FileName);
      ....
    }
 }

 protected void Button3_Click(object sender, EventArgs e)
 {
   if (FileUpload2.HasFile)
    {
      .....
      ViewState["file2"]=Server.MapPath("~/upload/" + FileUpload2.FileName);
      ....
    }
 }

    In button1_click handler,

    protected void Button1_Click(object sender, EventArgs e)
{
   if(ViewState["file1"]!=null)
      Label1.Text=ViewState["file1"].ToString();
   if(ViewState["file2"]!=null)
      Label2.Text=ViewState["file2"].ToString();
 }
