Hello! I have some questions about coreboot:
What are the most popular systems on which coreboot is typically used? What mainboards, southbridges, SoCs etc do these systems use? What is the most used part of code (for which system) in coreboot?

See the systems listed at https://coreboot.org/users.html
ChromeOS devices (Chromebooks, Chromeboxes, Chromebit, etc) are quite popular.
What mainboards, southbridges, SoCs etc do these systems use?
A variety.
What is the most used part of code (for which system) in coreboot?
What do you mean?

I guess that's the various Chromebooks, all of which ship with coreboot.

Chromebook (and related) reference mainboards live under mainboard/google/ in the codebase, but note that those are just that, reference designs.
From these reference designs OEMs that you may already know (Lenovo, HP, etc.) then create products which may (or may not!) have a subdirectory of their own under mainboard/lenovo/.
Then please refer to the source code for the components used, since that's a long list. Look at the Kconfig file (it's just a text file) in the subdirectory for a mainboard and you'll see which different components that board uses, in select SOUTHBRIDGE_.. etc. lines.

A core design principle of coreboot is to maximize code reuse across as many systems as possible. This is in contrast to common practice among commercial IBVs where a single full codebase per mainboard is not uncommon.
So I'd like to answer this your question with "almost everything for all systems" but in reality some code is central and other is not.
Code in {console,device,lib}/ is explicitly generic so that should have the largest coverage.

Just a note that this is not actually the case, the OEM variant firmware is always (at least in recent memory) able to be built as well, (see the mainboard/google/*/variants subdirectories). Yes it does include the reference design, sometimes as a "baseboard", where the variants simply provide their differences from the baseboard.
