Creating More Menu

Navigation Menus
. WordPress includes an easy to use mechanism for introducing customised navigation menus into a theme. In order to incorporate menu support into your theme, you need to add a few code segments to your theme files.
Function Reference
Register Navigation Menu
register_nav_menus()
register_nav_menu()
unregister_nav_menu()
Show Navigation Menu
has_nav_menu()
wp_nav_menu()

Register Menus
Firstly, in your theme's functions.php, you need to write a function to register the names of your menus. (This is how they will appear in the Appearance -> Menus admin screen.) As an example, this menu would appear in the "Theme Locations" box as "Header Menu".
function register_my_menu() {
  register_nav_menu('header-menu',__( 'Header Menu' ));  }

 add_action( 'init', 'register_my_menu' );
And this would make two menu options appear, header menu and extra menu -
function register_my_menus() {  

 register_nav_menus(      array(  
    'header-menu' => __( 'Header Menu' ),  

    'extra-menu' => __( 'Extra Menu' )      )    );  }
add_action( 'init', 'register_my_menus' );

Nivo slider Defect
    Warning : The permissions to the directory /home/username/sitename//wp-content/uploads/nivoslider4wp_files/ are invalid. Set them to 777 to be able to upload files.
First, the path is wrong on line 7 of file nivoslider4wp-panel.php. I changed it from:
$ns4wp_filesdir = ABSPATH.'/wp-content/uploads/nivoslider4wp_files/';
to:
$ns4wp_filesdir = ABSPATH.'wp-content/uploads/nivoslider4wp_files/';
Second, line 274 requires permissions 777 on the folder which is a MAJOR security issue. I changed it from:
<?php if (substr(decoct(fileperms($ns4wp_filesdir)),2) != '777') : ?>
to:
<?php if (substr(decoct(fileperms($ns4wp_filesdir)),2) < '755') : ?>
In my opinion these things need to be changed in the plugin core.

Create Dynamic Sidebar

Paste this code where you want to show..
  <?php // if ( dynamic_sidebar('sidebar-3') ) : else : endif; ?>
Paste this code in function.php
register_sidebar( array(
        'name'          => __( 'Secondary Widget Area', 'twentythirteen' ),
        'id'            => 'sidebar-2',
        'description'   => __( 'Appears on posts and pages in the sidebar.', 'twentythirteen' ),
        'before_widget' => '<aside id="%1$s" class="widget %2$s">',
        'after_widget'  => '</aside>',
        'before_title'  => '<h3 class="widget-title">',
        'after_title'   => '</h3>',
    ) );
Theme My Admin
FOR LOGIN PAGE
[theme-my-login default_action=login login_template=tml-login-form.php]
FOR REGISTER PAGE
[theme-my-login show_title=0 default_action=register register_template=tml-register-form.php]

FOR LOST PASSWORD PAGE

[theme-my-login show_title=0 default_action=lostpassword lostpassword_template=tml-lostpassword-form.php]
But now I'm not able to replicate this strategy for the profile page.
I've created a WP page for the themed profile and I've putted this shortcode in it's content:
[theme-my-login default_action=profile profile_template=tml-profile-form.php]
