[General] usage of "stay away"

Dear teachers,

Would you share with me your opinion concerning the following use of “stay away” in the adduced bellow sentences?

The doctor advised Jim to stay away from fattening foods.

stay away = avoid

He stayed away from school for weeks at a time.

stay away = be absent

He has to stay away from home overnight.

You must to stay away from me.

It calls for a solid one or two-day "stay away" from work to protest in a manner that will not expose people to the violence and intimidation of the police and the army.

stay away = a form of non-violent protest action

It does not follow from this that country voters in the Periclean Assembly outnumbered city voters 3: 1 because, as Aristotle noted ( Politics 1318), farmers tended to stay away.

Wherever possible they try not to have that but you may have to stay away.

Thank you for your efforts.

Regards,

V.
