and the size of the registration title: 800 x200px? or 1118,67 *150?

That's entirely up to you. The height of the registration canvas will never be larger than 200px so I don't really recommend going larger than that. The width should be at least the largest display you expect to support. So if your display is a fixed 800px width then that'll be fine for the width.

--> but in the page is a height of 150px. must i put 150px? which is the best width? sometimes the web is bigger or smaller?

In the "CB Login Module" there is a paramter"Login Redirection URL". In my case it is empty, so i should redirect to the current page but it is not working as I think. I´ve got several CB Login Module. One for guest, other for mobile version an another one for register. Just one is shown each time, but how can i know which "login redirect url" is used?

Redirecting the user back to where they came from when using the login module only works if they are using it on the page you want them to return to or if it's a Joomla access denied error (as Joomla will set &return). If you're just sending people to the login page it has no information to go off of to return them (it's based off the &return parameter in the URL at that point).

Joomla has no functionality that I'm aware of for 1 module for mobile and 1 for desktop. My guess is you need a Joomla template that has mobile only module positions by using @media CSS to hide/show as needed.

When I use, menu entry CB Login (Alias: cb-login), where am i redirected? Is i don´t have in the page any "Cb Login Module"?

If the login redirect is empty in this case then it'll always redirect back to your home page in this case.
