All of us know that "from now on" means starting from now, for example:

From now on, all of us have to turn our mobiles off.

But is this term assignable to such phrase?

From lesson three on…
(I mean starting from the lesson three…)

Thanks

"From now on" means "from this moment". More spesifically, it means strating from this moment or strating now. And it automatically implies that it will be that way into the future and not just happen in one little moment and stop and never reoccur.
