Question on keys when creating keystore for LTS version

Hello,

How many keys can I have when creating keystores in order to create the .apk? I notice that I need one separate one for each project. See my screenshot. It appears that I need to create multiple keys even for one keystore file. Is that correct? For the record, I’m using 2022.3.30 LTS.
