If you do this in a Visualforce Email and have a custom controller you can split on the new line character and then get those first five lines.
  
List<String> commentLines = new List<String>();

Integer i = 0;

for (String line : = comment.Body.split('\n')) {
    commentLines.add(line);

    i += 1;
    if (i == 5) {
        break;
    }
}

String shortenedComment = String.join(commentLines, '\n');
