The meaning of all and every is very similar but we use them in different ways. We use all with plural and uncountable nouns and every with singular nouns:
All donations will be sent to the earthquake relief fund.
All equipment must be returned by the end of June. (uncountable)
Every donation is appreciated.
We can use all and all of before determiners, but we don’t use every before determiners:
I invited all (of) my friends.
Not: …
every my friends
