Off in French

Answer 1

Sorry but phrasal verbs are not used in French. And it would be too complicated to explain each case.

Phrasal verbs in English are composed of a verb, giving the "action", and a particule which gives the verb a "spatial" and/or "negative" or "positive" sense.

Off is often "negative"

In French, this sense is given either in the verb itself,

He took off his shoes - il retira ses chaussures.

I paid off all my debts - J'ai réglé toutes mes dettes.

I called off the meeting : j'ai annulé la réunion.

To switch off (an electric device ...) - éteindre

Come off it - Arrête çà !!

or with a verb accompanied by an adverb

The negociations broke off. Les négociations ont été brutalement interrompues.

Moreover, the context can change the sense :

for example, To be off can be

s'en aller

I'm off - je m'en vais

Avoir arrêter

She's off drugs - Elle a arrêté la drogue (she stopped the drugs)

There are so many different cases it is impossible to list them all
