Before a number, 'alle' (all) can specify the complete group more precisely. The pattern is 'alle' + number, for example when referring to people or objects.

For regular time intervals, 'alle' (every) comes before a time expression, usually in the plural. This describes recurring events or processes.

You have to take the tablets every eight hours.
In 'alle Welt' (everyone), 'Welt' (world) is grammatically singular, so the verb is also singular. The expression is mainly colloquial and refers to a very large number of people.

Everyone knows this song by now.
'Alle naselang' (every few minutes) is used as a fixed adverbial expression and often appears with verbs for repeated contact or events. The expression is colloquial.

'Alle Jubeljahre' (once in a blue moon) is a fixed colloquial expression. It usually appears before or after the verb and describes something that happens only very rarely.
