Answer that was chosen as the BEST ANSWER

Mx. h

The lexical meaning is exactly the same for all four.

If you compel me to illustrate the differences in nuance from situations where they're actually used, it is probably around the level that you would call

For “どんな人” and “どのような人”, “どのような人” is a more polite choice of words, but their meanings are exactly the same. In comparison to the ways of asking “どういう人” and “どういった人”, there is a nuance where you are asking about . There is a nuance where you are asking どんな人 is their visual impression, such as whether they are tall, whether they are fat and how their physical appearance is.

For “どういう人” and “どういった人”, their politeness is also exactly the same. While “どんな人” is asking, there is a nuance where “どういう人” and “どういった人” is asking that person’s  such as “What have you done so far?”, “What kind of lifestyle have you lived?” and “What is he doing now?”

However, the thing is that this will turn out this way if you emphasize the differences, and there are also cases where they are actually used in exactly the same way.

There are differences in how to use them.

I think they are semantically the same; even if you check the Koujien [1], the same interpretations are listed.

[1] The Koujien (Eng. “Wide Garden of Words”) is widely regarded as the most authoritative dictionary on the Japanese language. However, there are people who make the mistake of using only this dictionary to back up their arguments, and nothing else.
