I would rephrase all of them as "so he could ____ it/them".

I shared my research results with him so he could verify them in his lab.
I told him my idea so he could test it in his lab.
I told him my new joke so he could tell it to you.

If you're willing to give up the definiteness of "my", you can do these more formulaic sentences.

I gave him some research results to verify in his lab.
I gave him an idea to test in his lab.
I gave him a new joke to tell you.

The more words you put before the modifying infinitive, the more likely the reader will lose the train of thought.

You can also rephrase with 'for' to indicate the subject of the infinitive.

I had some research results for him to verify in his lab.
I had an idea for him to test in his lab.
I had a new joke for him to tell to you.

navitasanAre sentences 1-3 correct

Number two is shaky, but the others are fine.

navitasando they have the assigned meanings?

They make only a tenuous connection. I would put it another way in formal writing, say it right out.
