Answer 4

special software, if it is on the phone, usually it is not worth it

Answer 5

Only with software on the phone. The software can not be installed remotely. Except social engineering. But that won't work with an iPhone. If with android you can still somehow force a person with social engineering to install something from apkshki (xs how do you do it with only a number), but in ios you can’t install applications without an app store. And no one will let such software go there.
Answer: Absolutely not.
