Some of those things on the list are very very rare cases but I just wanted to cover everything (or almost everything).

Dementia and drug use cause paranoia. That is very common. Some of other things that can include delusions and/or hallucination can be:

Withdrawal from benzodiazepines

Hallucinogen use

Pharmaceutical drug (abuse or side effects)

Can certain diseases cause paranoia similar to that seen in individuals with paranoid schizophrenia, even if they do not have the disorder?
