Can you give us more details what you exacly need?
You can execute sql code that will update that table.
You can go to phpmyadmin and update it from server menu.
You want to update table you created or user that belongs to database?

 </head>

  <body>

    <div class="login-container">
        <div class="login-header">
            <h4>Sign Up</h4>
        </div>
        <form method="post" action="save.php">
            <div class="login-field">
                <label for="name"></label>
                <input type="text" name="name" id="name" placeholder="Username">
                <i class="icon-user"></i>
            </div>
            <div class="login-field">
                <label for="email"></label>
                <input type="text" name="email" id="email" placeholder="Email">

 After that I don`t know how to change password ,
 in db, I have the faollowung fields:
 id, name, email, password, only
Member Avatar for milil

on your changepassword.php you have <form method="post" action="checkpassword.php"> so when you click change passwords that form will be called.
What I suggest is this. When you login put that user in session.
When you click on change password it will grab user ID from session and this new password you enterd from form. Your form is post method so you will have something like this:

$newPassword="";

if(isset($_POST["newpassword"])) {
    $newPassword=$_POST["newpassword"];
}

$USERID = "";

$_SESSION["USERID"] = "USERID";

$SQL="UPDATE `USER` SET `PASSWORD` = " . $newPassword ." WHERE `USERID` =" . $USERID . ";";

So what you need to do is next:
- When login put userid in session
- If you didn't create checkpassword.php please create it because your form is calling that
- Grab values from post method and session
- Update database
- Return value
