<p>'still' is already a difficult word.</p>
<p>still: Old English stille &quot;motionless, stable, fixed, stationary,&quot;</p>
<p>You know that old Xmas hymn: Stille Nacht (Silent Night) （Joseph Mohr, music Franz Mohr.）</p>
<p>&quot;Stille Nacht, heilige Nacht, alles schläft, einsam wacht.&quot;</p>
<p>still: &quot;even now, even then, yet&quot; (still standing, still waiting),</p>

I rewrote a bit your answer for clarity, but feel free to change it furthermore or roll back to your previous version. I'd suggest for being more beginner-friendly, you consider adding English translations to examples, as well as to use simplified characters when the OP uses simplified characters (I didn't realize at the beginning 還 = 还).

They are roughly interchangeable when they have roughly the same meaning, which you already listed. Is that surprising? By the way, you can probably simplify the meanings of 还 into *still* and *even*. The other distinctions aren't really standalone cases

OP already listed their different definitions. They don't seem to be interchangeable at all.

The meaning of 'still' may be the only one where either word-choices can be used in the same sentence, but there's still some subtle differences between them:

* `Fact 1 + 还 + Fact 2` **describes the facts without emphasizing any**.
* `Fact 1 + 还是 + Fact 2` **emphasizes the seriousness of** `Fact 1`**:** **despite** `Fact 1`**,** `Fact 2` **still occurs .**

Examples:

1. > 水浸眼眉了他还不逃命.
   >
   > His eyebrows are flooded and he won't run away.

   Describes a situation without emphasizing any part: Fact 1. 水浸眼眉了 and Fact 2. 他还不逃命.

   > 水浸眼眉了他还是不逃命.
   >
   > His eyebrows are flooded, he still won't run for his life.

   Emphasizes the seriousness of 水浸眼眉: despite 水浸眼眉了, 他还是不逃命.
2. > 天黑了还不回家.
   >
   > Not going home when it gets dark.

   Describes a situation without emphasizing any part: Fact 1. 天黑了 and Fact 2. 还不回家.

   > 天黑了还是不回家.
   >
   > Still not going home after dark.

   Emphasizes the importance of 天黑了: despite 天黑了, he still 不回家.

你还不同意吗 implies *(given something aforementioned), you **still** disagree?*

你还是不同意吗 implies *(given something aforementioned), your attitude/stance **is still** no/disagree?*

'still' is already a difficult word.
still: Old English stille "motionless, stable, fixed, stationary,"
You know that old Xmas hymn: Stille Nacht (Silent Night) （Joseph Mohr, music Franz Mohr.）
"Stille Nacht, heilige Nacht, alles schläft, einsam wacht."
still: "even now, even then, yet" (still standing, still waiting),
还huán：回到原处或恢复原状：还乡。还俗。衣锦还乡。返老还童。
还hái：依然，仍然：这本书～没有看完。
Grammar in general, has never addressed, will not answer, the question, "Why is that not acceptable?" People will just tell you, "Doesn't sound right, we don't say it like that." So you are in pursuit of inexplicable answers. Linguists have a favourite phrase, 'non-felicitous', meaning 'It sounds wrong, but don't ask us why it's wrong!'
A quick survey gave this result for your example sentences.
1. 我解释了这么多遍，你还不懂？OK to use 还是 here.
2. 她有一个弟弟，还有一个妹妹. NO ‘还有’是一词。
3. 这个电影很好，我看过，还想看. OK to use 还是 here.
4. 我还好。NO 我还是不好。X 你饿不饿？我还好。 OK 我还是不饿。 OK 
5. 还留过学呢，英语这么差。NO can't use 还是 还是留过学的呢。OK
6. 他说的话，你还听吗？OK can use 还是 here.
7. 他比姚明还高。NO can't use 还是 还 here means than 还要高 OK
8. 父母不同意他去，可是他还是去了。NO can't use 还
9. 你喝茶还是喝咖啡？OK can use just 还
10. 你还是快点走吧。NO can't just use 还 here.

Maybe, 还 + verb can be changed more easily to 还是。
