按题主给出的html，可以这样:

Document document = Jsoup.parse(html);
Elements elements = document.select("td br:lt(4)");
for (Element element : elements) {
    System.out.println(element.previousSibling());
}

应题主需求，可以改为:

    Document document = Jsoup.parse(html);
    Elements elements = document.select("td");
    for (Element element : elements) {
        Elements brs = element.select("br:lt(4)");
        if(StringUtils.isNotBlank(brs.toString()))
            for (Element br : brs) {
                System.out.print(br.previousSibling().toString().concat(" "));
            }
        else
            System.out.println(element.html());
    }
