There are many ways to do it. Here is one solution, which is based on the Data td (the one withe the 'lm' class):

HtmlAgilityPack.HtmlDocument doc = new HtmlAgilityPack.HtmlDocument();
... load the doc ...

foreach (HtmlNode node in doc.DocumentNode.SelectNodes("//td[@class='lm']/../td[5]"))
{
    Console.WriteLine("node=" + node.InnerText);
}
