1. Create the folder: App/Observers/, edit each Observer as you need and place them there.
2. In Providers/AppServiceProvider, add each Observer you created in the boot method, like:

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap any application services.
     *
     * @return void
     */
    public function boot()
    {
        //Read it like: Your model::observes(YourModelObservers)
        \App\Models\MyModel::observe(\App\Observer\MyModelObserver::class);
    }

    /**
     * Register any application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}
