Looking at your values, you just have to loop $name and print them simultaneously with $subtitle and $file index values like below:
<?php
foreach($rows as $row) {
$title = explode("*" , $row['title']);
$subtitle = explode("*" , $row['subtitle']);
$file = explode("*" , $row['file']);
foreach($title as $index => $title_value){
echo 'Title:' ,$title_value,PHP_EOL;
echo 'Subtitle:',$subtitle[ $index ],PHP_EOL;
echo 'File:',$file[ $index ],PHP_EOL;
echo "----------",PHP_EOL;
}
}

When you explode your row data you have an array, so you can do this:
foreach($name as $key => $value){
echo 'name - '.$value;
if(isset($subtitle[$key])){
echo 'subtitle - '.$subtitle[$key];
}
if(isset($file [$key])){
echo 'file - '.$file [$key];
}
}
But if you are not sure that number if names is equal to numbers of subtitle and file, you can get the highest count of array elements and do it like that:
for($i = 0; $i < $highestCount; $i++){
...
if(isset($subtitle[$i])){
echo 'subtitle - '.$subtitle[$i];
}
....
}

You can just try:
$id = $_GET['id'];
$get_history = mysqli_query($mysqli, "SELECT * FROM history WHERE id=".$id."");
$row = mysqli_fetch_assoc($get_history);
these three below will get the data that is exploded from the original data.
$title = explode("*" , $row['title']);
$subtitle = explode("*" , $row['subtitle']);
$file= explode("*" , $row['file']);
to display them:
Title : $title[0]
Subtitle: $subtitle[0]
File: $file[0]
---------------------
Title : $title[1]
Subtitle: $subtitle[1]
File: $file[1]
---------------------
Title : $title[2]
Subtitle: $subtitle[2]
File: $file[2]
Let me know if this works :)
