Thats basically the Same like with adding one ball. Just for multiple times. Now there are 2 ways. Either just do this 10 times with a for (int i = 0 ; i < howManyNewBalls; i++) around the whole thing. Or you change the code a bit for more efficiency.

void mousePressed() {
  if ( mouseButton == LEFT ) {
    if (!firstMousePress) {
      for (int i=0; i < bola.length; i++) {
        strokeWeight(2);
        warna = color(random(255), random(255), random(255));
        bola[i] = new Benda(mouseX, mouseY, random(30), warna);
      }
      firstMousePress = true;
    } else {
      Benda[] bolaTemp = new Benda[bola.length + 10];
      for (int i = 0; i < bola.length; i++) {
       bolaTemp[i] = bola[i]; 
      }
      for (int i = 0; i < 10; i++) {
        bolaTemp[bolaTemp.length-(i+1)] = new Benda(mouseX, mouseY, random(30), warna);
      }
      bola = bolaTemp;
    }
  }
}
