    Route::group(['prefix' => 'categories', 'middleware' => ['superadmin', 'ad','editor']], function () {
        Route::get('/index', ['as' => 'back.categories.index', 'uses' => 'backend\CategoriesController@index']);

my kernel.php

'admin'=>\App\Http\Middleware\CheckAdmin::class,
'superadmin'=>\App\Http\Middleware\CheckSuperAdmin::class,
'ad'=>\App\Http\Middleware\CheckAd::class,
'editor'=>\App\Http\Middleware\CheckEditor::class,

my checkadmin (check if user is one of the admin) middlware this one worked

class CheckAdmin
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if(Auth::check() && Auth::user()->role_id !='4'){
            return $next($request);
        }
        return redirect()->route('backend-login');
    }
}

my checksuperadmin middleware

class CheckSuperAdmin
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if(Auth::check() && Auth::user()->role_id =='1'){
            return $next($request);
        }
        Session::flash('notsuper','only super admin can access this page');
        return redirect()->route('backend');

    }
}

my checkad( check for normal admin) middlware

class CheckAd
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if(Auth::check() && Auth::user()->role_id =='2'){
            return $next($request);
        }
        Session::flash('notadmin','only admin can access this page');
        return redirect()->route('backend');

    }
}

my checkeditor middleware

class CheckEditor
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if(Auth::check() && Auth::user()->role_id =='3'){
            return $next($request);
        }
        Session::flash('noteditor','only editor can access this page');
        return redirect()->route('backend');

    }
}

i don't know why but all the checksuperadmin, checkadm, checkeditor always return false
