I bought a honda crv 2004, but I can't know what does those buttons stand for in it.
Th rounded button with red border:

The first looks like a button for disabling the window lifters on the rear seats and perhaps the passenger seat. I have the same button on my 2016 Toyota RAV4 hybrid, although it has a better symbol on it. I might be incorrect, though. So you should try the button and see if my guess was correct. Or, it could be related to operating the central locking system.
The third is fog lights, obviously.
Of the second, I do not know unfortunately. Perhaps somebody can come up with a different answer or edit my answer. Could be related to cruise control, but usually there are speed adjustments and other features on the cruise control and this is just one button.
Mate I'll make this like icing on top of a super cake.
