Answer 1

Change:
$query = "INSERT INTO account_info(user_name,user_passemail) VALUES ('$Username','$Password','$Email');";
To:
$query = "INSERT INTO account_info(user_name,user_pass,email) VALUES ('$Username','$Password','$Email');";
You forgot to add a comma ","

Answer 2

Warning mysql_query, mysql_fetch_array,mysql_connect etc.. extensions were deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0.
Instead, the MySQLi or PDO_MySQL extension should be used.
YOu miss the coma between user_pass and email in column name
$query = "INSERT INTO account_info(user_name,user_pass,email) VALUES ('$Username','$Password','$Email');";
try mysqli
//db connection
global $conn;
$servername = "localhost"; //host name
$username = "username"; //username
$password = "password"; //password
$mysql_database = "dbname"; //database name
//mysqli prepared statement
$conn = mysqli_connect($servername, $username, $password) or die("Connection failed: " . mysqli_connect_error());
mysqli_select_db($conn,$mysql_database) or die("Opps some thing went wrong");
//require_once('mysql_conn.php');
$Username = mysqli_real_escape_string($_POST['Username']);
$Password = md5(mysqli_real_escape_string($_POST['Password']));
$Email = mysqli_real_escape_string($_POST['Email']);
//$query_check ="SELECT user_name FROM account_info WHERE user_name = '$Username'";
// $retval_check = mysqli_query( $query_check, $conn );
if(!empty($Username))
{
$stmt = $conn->prepare("SELECT user_name FROM account_info WHERE user_name =? ");
$stmt->bind_param('s',$Username);
The argument may be one of four types:
i - integer
d - double
s - string
b - BLOB
//change it by respectively
$stmt->execute();
$get_result =$stmt->get_result();
$row_count= $get_result->num_rows;
//$row_count= $stmt->affected_rows;
$stmt->close();
//$conn->close();
}
if( $Username == "" || $Password == "" || $Email == "" ){
echo"Please fill the field";
} else{
if($row_count>0){
echo"Username Already Taken";
} else {
//$query = "INSERT INTO account_info(user_name,user_pass,email) VALUES ('$Username','$Password','$Email');";
^^^^^
//$retval = mysql_query( $query, $conn );
$stmt1 = $conn->prepare("INSERT INTO account_info(user_name,user_pass,email) VALUES (?,?,?)");
$stmt->bind_param('sss',$Username,$Password,$Email);
The argument may be one of four types:
i - integer
d - double
s - string
b - BLOB
//change it by respectively
$stmt1->execute();
//$get_result1 =$stmt1->get_result();
//$row_count1= $get_result1->num_rows;
$row_count1= $stmt1->affected_rows;
$stmt1->close();
$conn->close();
if($row_count1>0)
{
echo "<script>";
echo "alert('Thank you for registering Enjoy the game !')";
echo "</script>";
}
else
{
echo "<script>";
echo "alert('registeration failed')";
echo "</script>";
}
echo "<script>";
echo 'location.href = "menu.html";';
echo "</script>";
}
}
