Answer 1

try this query to insert from another table
SELECT * INTO TABLE2 FROM student
use where condition on student table as where student.column value to select checked values

Answer 2

Applied same above things with checkbox input field
echo '<input type="checkbox" name="status" value="'.$id.'" 'if($row['present_field_of_database']) ? 'checked' : ''
'>'.ucfirst($rows['f_name']).'';

<div class="attendance">
<form accept="att.php" method="POST">
<?php
$sel_sql = "SELECT * FROM student";
$run_sql = mysqli_query($conn,$sel_sql);
while($rows = mysqli_fetch_assoc($run_sql)){
$id = $rows['id'];
// if your $id value is right from $rows['id'] then
// change your student table name to the another table where available status of the student
$wh_sql = "SELECT * FROM student WHERE id=".$id;
$run_wh_sql = mysqli_query($conn, $wh_sql);
$Wh_rows = mysqli_fetch_assoc($run_wh_sql);
// add student present or absent value to the rows data
$rows['status'] = $Wh_rows['status'];
}
// set value as A or P respectively absent or present add jquery plugins for onclick event while client click on checkbox change value respectively
echo '<input type="checkbox" name="status" value="'.$rows['status'].'" 'if($rows['status'] == "A") ?'checked': '' '>'.ucfirst($rows['f_name']).' onclick= "$(this).val(this.checked ? P : A)"';
?>
