The catle stands above(over) the lake?

[keannu]

Is it true that over means just vertically higher position, while above means all the higher positions either vertically or diagonally? That's why the below's over doesn't make sense?

ex)The castle stands above(over) the lake?

I am not a teacher.

Yes, that sounds like a good rule. By the way, I think you meant "castle". I read it "cattle" at first, which doesn't work at all.

[SoothingDave]

I was picturing cattle walking on water.

[Barb_D]

Me too. (The cattle walking on the water. Holy cow!)

If you say the castle is over the lake, it sounds like it is magically hovering there. That could work in some fairy stories, though!

[Khosro]

I would put it this way: The castle does not cover any part of the surface of the lake. It's just in a higher position than the lake. That's the reason we say "above the lake". If it were mid-day the shadow of the castle would not fall on the lake.

That's why the below's over doesn't make sense?

ex)The castle stands above(over) the lake?

Say "the over below". You can't say "below's over" or "below's sentence".

In "the over below", "below" is adverb.

[Raymott]

Say "the over below". You can't say "below's over" or "below's sentence".

In "the over below", "below" is adverb.

And if you really want to be understood, quote 'over'.
I wouldn't use 'below' like this either. I'd say, "the 'over' in the sentence below."
