If the original game runs on Linux, sure.

Otherwise if the original game runs on proton/wine/bottles whatever, I guess it depends and you need to try.

My two cents: if the game already run on Linux, doesn't matter if it's emulated native or what, will run both original and pirated.

In general, the Denuvo bypasses will not work. Other games should generally work fine, with the appropriate cracks.

You can use protondb as a guide to what will and will not work. If it is pirate or original usually doesn't really matter. You can use lutris to make your life easier. If you download from a site that needs you to install extra programs to run the game, just choose them as if they are the game.exe, run it to install, repeat with all needed programs, then change back to the game.exe and play

If it's a true crack then as long as the game itself works on linux then the cracked version can. You listed the current exception (as hv bypass is not a type of crack).

Yes, but in my experience, its more work to get it to work. Some games will launch immediately, others you will find yourself tweaking proton settings or installing dependencies. On windows every cracked game just launches immediately.

I've basically grabbed every fitgirl repack that interested me for the past few years and have installed and played it on linux. Literally just use steam to install non steam game. Set your proton compat and enjoy.

Yes, they all work. 🤦🏼

I've had issues with repacks and Lutris. One of the reasons I still dual boot, I already have a large collection of mostly repacks.You're probably more likely to get it to work with an uncompressed installer, and much more likely with already installed files.
