adjectivesget-passivegrammarpassive-voiceverbs
I am not sure how to explain these phrases to a nonspeaker of English.
Have all these examples the same form?
Get (v) married (v past participle) or it is Get(v) married (adj) ?
Get (v) engaged (v past participle) engaged (adj) ?
Get (v) divorced (v past participle) divorced (adj) ?
Get (v) promoted (v past participle) promoted (adj) ?
Could somebody help me?
Both are idiomatic but "I will be killed" is the more widely used phrase:

It's perfectly good. Some would not approve of it in writing, mostly because of the colloquial phrase "get rid of".
[A few dinosaurs still object to the preposition at the end, but that so-called rule was nonsense when it was invented, and is now mostly recognised as nonsense].

"Get" + "married" can be either an adjectival passive or a verbal one:
In the former, "married" is an adjective; in the latter a past participle verb.
In [1] the by phrase makes it clearly verbal, so "married" is a verb here. In [2] there is no explicit or implicit agent, and even though "married" (unlike "engaged"), cannot combine with "become" (*“They became married”), "married" is still an adjective here with a meaning similar to "They are marrying each other".
"Get" + "engaged" is always an adjectival passive. "Engaged" is morphologically related to the past participle verb, but its meaning has changed so it is no longer comparable to a verbal passive. Further evidence of adjectivehood comes from the fact that it can combine with “become”, as in “They became engaged last month”. Only adjectives can combine with “become”.
