All of those you mentioned are capable of being certified for ETOPS.
But it actually depends on the particular airline that wants to operate them; this deals with their operating experience with that aircraft type, procedures, equipment on board, maintenance etc.
To give you an example, Tahiti based Air Tahiti Nui operates an A340 Airbus (two more are due for delivery if they haven't arrived already).
They originally wanted to use a Boeing 767, but because they were a brand new airline at the time obviously with no 767 experience, let alone on long overwater routes, they wouldn't have had enough ETOPS certification if any. ie, they may have been given 60 minutes ETOPS rather than say, 180 or whatever was required.
Hence they had to opt for the four engined Airbus, which I might add, they are totally impressed with.

In most countries 60 minutes is the maximum allowable distance for a two engined aircraft operating on one engine to go from an adequate airport (ie 430nm in a 767). Therefore ETOPS is anything over 60 minutes, so by definition there isn't a 60 minute ETOPS.
