AND THE WINNER IS!!!

Here are the entries for the crack the code contest
1.. @hasanulbasri
I chose 6.0.0 because that number is contained in many puzzles ,, 2 also there are two numbers, one number in the first box and one in the third box ,, but if you see the number 0 contained in the third and fifth boxes , the number 2 has been proven wrong, because the third box also contained the number 6 in the first and second boxes, and the first and second box is only one right number ,,,
Ok that's it, hopefully my answer is correct
Thanks @etemi

My answer is 0.4.2
Box 4 obviously nullifies 7,3,8, so from box 5: 0 is a part of the code (position yet to pointed out)

Box 3: two numbers correct but wrongly placed. With 0 being a certain digit in the code, wrongly placed in box 5 and 3,it therefore comes as the first digit

Box 1: 6 can't be the correct and well placed digit because 0 already has that position ; 8 is nullified from box 4,so 2 is the correct and well placed digit.

So far, the code is 0 _ 2

Finally,from Box 1,since only one digit (2) is correct but wrongly placed, others have been nullified. Also, Box 1 says one number is correct and well placed and 6 is the first digit. Box 2 says one number is correct but wrongly placed and 6 is the first digit again. So because 6 can't have both properties at the same time it's nullified.

Looking at 1... The code can't be 0.1.2 because Box 2 says there is one correct but wrongly placed number so 1 is nullified.

So I'm left with 4 which, from Box 2 is correct but wrongly placed as third digit.

Final answer: 0.4.2

4.. sanoza
0.6.2
Box 1 and Box 2: We can't find any answer yet
Box 3: 6 and 2 are correct numbers, 2 was meant in the box 1 and 6 in the Box 2. 2 is the third key and 6 can be the 1st or 2nd one. we'll find out later.
Box 5: 0 is a correct number because 7 and 8 are rejected by box 4.
6 is wrong placed in box 2 and box 3 so the right place for it is in the middle and finally the order is clear now 0.6.2
