It was an error on my part, I wrote a wrong symbol

This

void four() {
  temp = dht.readTemperature();
  if ((distance < 50) && (temp < 40)) {
    digitalWrite(relay2, LOW);
  }
  if ((distance < 50) && (temp > 40)) {
    digitalWrite(relay2, LOW);
  }
  if ((distance > 50) && (temp < 40)) {
    digitalWrite(relay2, LOW);
  }
  if ((distance) > 50 && (temp > 40)) {
    digitalWrite(relay2, HIGH);
  }
}

Can be simplified to:

void four() {
  temp = dht.readTemperature();
  if ((distance) > 50 && (temp > 40)) {
    digitalWrite(relay2, HIGH);
  }
  else {
       digitalWrite(relay2, LOW);
   }
}
