In class .paidocontainjsjl you put the justify-content: center; and in the images you put the margin the way you want, as it is 20px I suggest margin: 0 10px;

* {
  margin: 0;
  padding: 0;
}

@import url('https://fonts.googleapis.com/css2?family=Poppins:wght@500;600;700;800&display=swap');

.paidocontainjsjl {
  display: flex;

  flex-wrap: wrap;
  background-color: antiquewhite;
  padding-top: 90px;
  padding-bottom: 90px;
  font-family: 'Poppins', sans-serif;

  justify-content: center;
}


#humcentrimmm {
  position: absolute;
  top: 30px;
  left: 50%;
  z-index: 1;
  transform: translateX(-50%);
}

#humcentrimmm h1 {
  text-transform: uppercase;
  font-weight: bold;
  font-size: 37px;
}

.boxdaimgsds {
  position: relative;
  z-index: 10;
  width: 200px;
  margin: 0 10px;
}

.boxdaimgsds img {
  width: 200px;
  z-index: -99;
  margin-top: 40px;
}

.boxtexto {
  width: 200px;
  position: absolute;
  bottom: -20px;
  margin-top: -100px;
  background-color: salmon;
  padding-top: 10px;
  padding-bottom: 10px;
  text-align: center;
  color: #fff;
  font-size: 23px;
  font-weight: bold;
  z-index: 888;
  text-transform: uppercase;
}

.boxtexto::after {
  content: "";
  position: absolute;
  left: 0;
  bottom: 50px;
  background-color: salmon;
  clip-path: polygon(0 78%, 100% 93%, 100% 100%, 0% 100%);
  width: 100%;
  height: 100%;
}

@media (max-width:1087px) {
  .boxdaimgsds {
    margin-top: 50px;
  }

  #humcentrimmm {

  .boxdaimgsds img {
