Compare the value that comes from the bank with the skill array with the function in_array() if find assigns $selected to the selected value. Then mount the template with printf() .

while($row2 = $rs2->fetch_assoc()) {
    $selected = in_array($row2['tag'],$habilidades) ? 'selected="selected"' : ''; 
    printf('<option value="%s" %s>%s</option>', $row2['ID_Tag'], $selected, $row2['tag']);
}
