1. I _think_ the APK from Signal's site uses (or at least offers and then chooses based on your OS) a different non-Google way of sending you notifications. Not sure, check this again. DO NOT USE APKs from random sites or GitHub repos.
2. I don't know what you are asking exactly.
If you are asking for implications of answers to the first question for the privacy of Signal convos on iPhones (given iPhones are "locked down" (whatever that means?)) then I don't see any but my answer to 1. is uncertain and likely incomplete anyway. Note that surveillance via notification timing analyses has been reported in the past.
If you are asking whether Signal convos are less private (from who?) on iPhones compared to what exactly?, then I'd say that the Signal app itself is as good as on e.g. some Android flavour but that it of course depends (like any other app) on the OS playing ball. _In theory_ the OS could happily screenshot everything. Not saying this happens on iOS but it'd be possible and unnoticable. For something actually resembling privacy on a smartphone you should be using GrapheneOS anyway.
3. Yes.
4. Define "safe". Anyone knowing your username can message you. However, you can easily rotate your username without losing existing chats/contacts initiated with your old username.
5. No.
Remember: I'm just a random dude on the internet. Signal has an ok blog/documentation which helps you verify my claims.
