Answer 1

Route::get('/register', 'Signup_controllers#register');
You're including controllers within Controllers and alsorts of things are wrong with your code that are going to cause you problems
I'd consider reading the documentation to understand how Laravel works

Answer 2

You are using Resource Controllers incorrectly. See Laravel Documention.
https://laravel.com/docs/5.4/controllers#resource-controllers

Answer 3

change:
Route::resource('/guestcheckout', 'Signup_controllers#guestcheckout');
to
Route::post('/guestcheckout', 'Signup_controllers#guestcheckout');
and do the same thing for other routes, replace resource with post or get for your needs
Laravel resource routing assigns the typical "CRUD" routes to a
controller with a single line of code. and you call it like this :
Route::resource('photos', 'PhotoController');
