You haven't used the same names for your cookies. Change your code like below:
setcookie("c1",$a,time()+3600);
setcookie("c2",$b,time()+3600);
setcookie("c3",$c,time()+3600);
echo "First name:-".$_COOKIE['c1']."<br>";
echo "Email:-".$_COOKIE['c2']."<br>";
echo "Contact number:-".$_COOKIE['c3']."<br>";
