Page Layout ⇒ Multiline footer

[Yeth]

Hello,
I would like to have a multi-line footer.
I succeeded to make the second part of the footer but I want to add another part above this.
I tried to look for an answer but I found nothing.
Please, if anybody can help me, he's more than welcome.

This hardly depends on the used class. Depending on the used class you have to use a package like scrlayer-scrpage or fancyhdr. Some classes may also provide their own page style interface. So if you need more help, please show us a minimal working example.

This is neither minimal nor complete and there are mistakes like loading hyperref before titlesec.→https://latex.org/forum/viewtopic.php?p=111553#p111553

However, read the documentation of the used page style package to learn how to change the page header or footer (see, e.g., the package links in my previous comment or—better—read he TeX distribution manual to find out how to find the installed manual).

I don't know what minimal means, so I just copied the beginning of the code.
I'm trying to change a template from Word to Latex, so I'm trying to be the most faithful.
Thank you for your help.
