Out of those options, I'd think that the "IM doorbell" would be the most annoying / disruptive, at least for me personally. The other things are probably ones I could tune out. Not sure about the "teen buzz" one though, and if I'm old enough to have lost the ability to hear it.
Edit: Just checked Wikipedia:
The device is typically heard by people less than 25 years of age because the ability to hear high frequencies deteriorates in humans with age (a phenomenon known as presbycusis).
So it'd be marginal in my case and I'd probably be able to hear it, at least somewhat.
