Answer 1

You might have typo here !! it should be..
<input type="hidden" name="ques" value="<?php echo $ans_id; ?>" />
Other thing, you can add get param to action link it self.
<form id="add-comment" action="comment_submit_process.php?<?php echo $answer['id']; ?>" >

Answer 2

Instead of setting the ans_id, every time to the hidden field .
Generate a string of ans_id seperated with "," until while loop ends append the string and assign that value to the hidden field and in form action page you can get that value and generate van array from that string with delimiter ",".Now you can have the array of ans_id in your form action page
$answer_array = "nothing";
while($answer = mysql_fetch_array($ans))
{
if( $answer_array == "nothing")
$answer_array = $answer;
else
$answer_array .= ",".$answer;
}
<input type="hidden" name="answer_arr" value="<?=$answer_array?>">
In Form action page you can get that hidden value
$ans_array= explode(",",$_GET['answer_arr']);

Answer 3

You can echo answer_id in form action tag as additional parameter like this:
<form id="add-comment" action="comment_submit_process.php?ans_id=$ans_id" >
//Your stuff here
</form>
in comment_submit_process.php you can identify answer by
$ans_id=$_GET['ans_id'];
You can do further processing by using $ans_id
Edit:
change this line:
<input type="hidden" name="ques" value="<?php echo $_GET['$ans_id'] ?>"
to:
<input type="hidden" name="ques" value="<?php echo $ans_id; ?>" />
so that value of that field would be $ans_id fetched from DB.
