Legal Question in Criminal Law in Texas

There is no limit, although to have greatest effect and not to cause the judge to want to cut off the statements one should be reasonable. I have seen situations where one person spoke on behalf of themselves and a couple of other family members, expressing the other's pain and suffering. (So if 3 spoke and included statements from 3 others each, 9 people would be covered.) But legally, there is no limit. (And, some judges, especially depending on the offense, would encourage each person to talk as a way to help heal.)
