There is no digit that can replace the ? in 2?67 to make it divisible by 4.
All multiples of 4 are even, 2?67 is an odd number and so cannot be a multiple of 4.
To determine what digit can be placed in the blank to make a number divisible by 3, you need to ensure that the sum of all the digits in the number, including the blank, is divisible by 3. For example, if the number is 25_, you would calculate the sum of 2 + 5 + _ and check which digit (0-9) makes the total divisible by 3. Once you find the appropriate digit, you can fill in the blank.
0.
Add 6 to it and so 8784/18 = 488
29 is not divisible by 3 and how any digit will alter that depends on how that digit is to interact with 29.
If the number is divisible by 9 the sum of its digits (its digital root) must be divisible by 9. 5+6+8+9 = 28 The next multiple of 9 is 36 and that is 8 more. So the missing digit must be 8.

It depends on whether you mean the highest digit that you add or subtract or multiply by!
To make a number divisible by 10, its last digit must be 0. The last digit of 23483 is 3. Therefore, to make it divisible by 10, you should subtract 3 from 23483. This means the least number that should be subtracted is 3.
6 (or 0)
No single digit determines divisibility by 3.
