in front of, ahead, before, beyond, behind and after

Hello everybody,
I need your help.
Can you please make it clear when to use these words?
In front of, ahead,before,beyond, behind and after.
We will meet in front of/before or ahead of the city/school/store.(place)
We will meet before we reach the city/school/store. (time)
We will meet after/behind or beyond the city/school/store. (place)
We will meet after we arrive. (time)

Are all these sentences correct?

Thank you

after and before only use with time, they cannot use with place. So the first and the third sentences are not correct if we use after/before.

Thanks Waiyin :slight_smile:
