Through
gennem and igennem both mean through. Gennem is a preposition and comes before its noun:
| We drive through the forest. | Vi kører gennem skoven. |
Igennem can do the same job, but it can also stand at the end of the sentence, meaning all the way through:
| She slept through the whole night. | Hun sov hele natten igennem. |
Forbi
forbi is past — moving past something — and, after være, over, finished:
| The bus drives past the school. | Bussen kører forbi skolen. |
| The summer is over. | Sommeren er forbi. |
Herfra
herfra is her + fra, from here; the same pattern gives derfra (from there) and hvorfra (from where).
| From here you can see the sea. | Herfra kan man se havet. |
føre (to lead) is what roads and paths do: Vejen fører til byen.
| This road leads down to the harbor. | Denne vej fører ned til havnen. |
