Five o'clock is the time at which you are expected to arrive at the meeting or party or whatever it is.
It means that you are required to be at the designated location shortly before either 5:00 am or 5:00 pm (which of the two should be clear from the context).
O'clock means "of the clock." They're telling you a time. You should be there before 5:00 - but you should ask if they mean in the morning or in the evening!
True
It means right in front of you. When soldiers relate directions to the clock 3 oclock means right, 9 oclock means left 12 oclock means front, and 6 oclock means back.
"quatre heures"
NO. It is 33 minutes past SIX o'clock.

get yourself a cartesian circle, or just look at one online and translate it from there 3,6,9, and 12 would all be 90 deg increments.
breakfast is around 5 oclock.
5 o'clock
if you mean when installing a timing chain, the keyway or square notch should be at 12 oclock and the mark should be at 3 oclock
That's military speak for 5 oclock in the morning
8:00 oclock
