Hi @alycedetoldev,
I hope you are well today and thank you for your questions.
The first one is to separate the logo from the top menu. I wish it appeared at the top and the menu underneath it.
To achieve this please see the solution posted in the following topic.

The second thing is where I find the text that tells about the credits of the template. I do not want to remove it, but I want to translate it into my language.
Then just translate it as described on this page https://colorlib.com/wp/how-to-translate-wordpress-theme/ or by using this plugin Say what? – WordPress plugin | WordPress.org
Something that I do not know if they can help me, but I’ll ask anyway, is try to change the slider that comes in the template. I would like something like this site here:http://www.residentevil.com.br – I put the slider on attachments too.
Is there any way to do this? Or do I have to search for a plugin for this?
Yes you need to search for a plugin or develop custom code to achieve this.
Best Regards,
Movin
