I just have one question based on the examples I wrote:
2. Он такой умный что он может понять все = He is so clever that he can understand everything.
3. Oн такой умный человек что он может понять все = He is such a clever person that he can understand everything.

In this case такой, which as you mentioned an adjective, means both "such" and "so" in the English translation? Correct?
Yes, that's basically it, you got it
