I set 2 validation rules like this.

RULE 1
Complete at least one of field(species1 or species2)
RULE 2
Complete at least one of field(price1 or price2 or price3)

My code works fine as long as only one error. I mean, when both rules have an error, it does not hide error message however I corrected one of errors. It keeps showing error message. It does not do “return $valid”.

Im wondering if there is way to set multiple validation rules for multiple fields.

//RULE 1
function validate_species( $valid, $value, $field, $input ){
    if( !$valid ) {
        return $valid;
    }

    $species1 = $_POST['acf']['field_609b650e953ec'];
    $species2 = $_POST['acf']['field_609c4053b0ca8'];

    if (empty($species1) && empty($species2))  {
        $valid = 'Error message for Rule1';
    }
	return $valid;
}
add_filter('acf/validate_value/name=species1', 'validate_species', 10, 4);
add_filter('acf/validate_value/name=species2', 'validate_species', 10, 4);

//RULE 2
function validate_price( $valid, $value, $field, $input ){

    if( !$valid ) {
        return $valid;
    }

    $price1 = $_POST['acf']['field_609de26de0b75'];
    $price2 = $_POST['acf']['field_609de2b939a27'];
    $price3 = $_POST['acf']['field_609de324a1398'];

    if (empty($price1) && empty($price2) && empty($price3))  {
        $valid = 'Error message for Rule 2';
    }

	return $valid;
}
add_filter('acf/validate_value/name=price', 'validate_price', 10, 4);
add_filter('acf/validate_value/name=tokka', 'validate_price', 10, 4);
add_filter('acf/validate_value/name=jissai', 'validate_price', 10, 4);

This solved my question!
