With a reference note, you should be able to. That is, if you hear a G1, and then a G2, a competent musician should be able to easily tell that it’s an octave. You might not know that the pitch class is G. But you should be able to identify the interval as an octave, AKA a note in the same pitch class.
Octave equivalency (the idea that notes an octave apart are the same) is a cultural idea. If you're in a culture with octave equivalency (which I can strongly assume you are by your use of the English language), then it's probably beneficial to you to learn to hear octaves as the same note.
It's something to practice. You focus on the interval. I think it could be more difficult on different instrument. As a bass player octaves are very essential and after a certain amount of time I didn't even needed to think about it anymore. Same goes for most frequently used intervals.
? Are you talking about octaves?
Yes.
Yes, you're supposed to be able to hear that A at 440, 415, 392, and 466 are all an A.
I giggled
Don't forget 432 Hz!
Octaves anyone?

Yes. Welcome to the party. Throw in played by different instruments. I personally don’t bother and hope it comes to me through osmosis.
on its own with no context? No, unless you have perfect pitch. If hearing both you should be able to tell with good relative pitch.

Not necessarily, since there is such a thing as microtonality. That said, if you're talking about octaves, then yes.
