The Japanese translation is quite nice except the tense.
「…。」と、（先生は）指示しました／指示した。

thanks, updated..

In the English version of the first example, perhaps "just those" instead of "(just) people."
Also, I don't know how they do it in schools abroad, but in Japan, the teacher normally says "should stand up" instead of "should sit down."

I guess this is half way between a 'polite command' and a 'fairly forceful request'.

'[The teacher]' isn't explicitly in the Japanese version, but the English might look odd without it.

'(just)' wouldn't be natural in the English - the だけ in the Japanese doesn't explicitly tranlate.

The coloring in ex #1248 is very confusing. The 'し' looks to be part of '早く', which is not the intention, if I understand correctly.

fixed.
