iCake you helped a lot now everything is 100% clear.

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?
