If you want to test one-by-one: 

boolean algumSelecionado = jcbx1.isSelected() || jcbx2.isSelected() || jcbx3.isSelected() || jcbx4.isSelected()
                        || jcbx5.isSelected() || jcbx6.isSelected() || jcbx7.isSelected() || jcbx8.isSelected();

Or a more dynamic solution if JCheckBox is inside a JPanel: 

boolean algumSelecionado = false;

for (Component c : jpnl.getComponents()) {
  if (c instanceof JCheckBox && ((JCheckBox) c).isSelected()) {
    algumSelecionado = true;
    break;
  }
}
