[Grammar] 'When' clauses

[Mr.Lucky_One]

Hello, I've got a question about the sentence below.

We made popcorn when he came.

I have some variants of its interpretation. Here they are:
1. We had made popcorn when he came.
2. We made popcorn when he had come. (We waited for him to come, we didn't want to start making popcorn without him.)
3. We were making popcorn when he came.

May the original sentence be interpretated as all my variants? I especially would like to know whether the second variant was grammatical and whether it ment the same as the sentence in brackets.

1. Means "We had finished making the popcorn before he arrived".
2. Ungrammatical.
3. Means "We were still in the process of making popcorn when he arrived".

The original means that we only started making popcorn after he arrived. Only #1 and #3 are grammatical. Neither of them means the same as the original sentence.

Thanks a lot.
If I said "We started making popcorn just as he came.", might it have a meaning like #2? I mean the sentence in brackets. When I wrote sentence #2, I thought it would mean the same as one in brackets. What is the best way to say it?

#2 doesn't mean anything, it's ungrammatical.
