The highest digit is one less than the base used for counting.
So in binary (base 2), the highest digit is 1
In octal (base 8), the highest digit is 7
In decimal (base 10), the highest digit is 9
In hexadecimal (base 16), the highest "digit" is 15. The symbols A, B, C, D, E and F represent the "digits" 10, 11, 12, 13, 14 and 15.
And so on.
Highest number is 7
Highest 2-digit number = 99 Highest 1-digit number = 9 Highest possible sum from 2, 2-digit numbers = 198 Highest possible sum from 2, 1-digit numbers = 18
987654321 is the highest nine-digit number with no repeated digits.

The highest place value in a decimal number is the left most digit, also the first digit.
The highest two-digit prime number is 97. Out of that group, the highest (and only) prime number is 71.
The highest four-digit number using three odd digits is 9997. This is achieved by using the digit '9' three times (the highest odd digit) and the next highest odd digit, which is '7', to complete the four-digit requirement. Therefore, the combination of three '9's and one '7' results in the number 9997.
