Artem_A,
теперь

var newCicles = document.querySelectorAll('.circle');

и в цикле

c4.circleProgress({
      startAngle: -Math.PI /2 * 8 ,
      lineCap: 'round',
      value: c4.data("value"),
      thickness: 4,
      fill: {color: '#19bd9a' },
      emptyFill: 'rgba(4, 115, 120, 1)'
  }).on('circle-animation-progress', function(event, progress, stepValue) {
    $(this).find('strong').text((100 * stepValue).toFixed(0) + '%');
  });
});
