Why do people wait several rings before answering, when they have the phone in their hands from the get go?
For me, it's generally anxiety. Unexpected phone calls (or unexpected contact in general) tends to send me into panic mode, and I need to take a moment to right myself and decide whether or not I want to answer it. It's my understanding, though, that most people do this because they don't want to seem overeager or over-available (if that makes sense).

Why do some people pretend not to know who's calling, even though most phones have caller ID things now?
I suspect it's just culturally ingrained in us. You answer the phone with "Hello?" as though you don't know who's calling. It's just what you do. Everyone expects it. If some guy named John was calling you, and you answered straight away with "Hey, John," it would almost certainly throw him off.
