There would need to be a digit which represents Ten. This would be the largest digit. Any number can be represented in any number-base system, so there is no 'largest number' just largest digit. Base eleven is not commonly used as some of the others (like hexadecimal, which uses letters A-F to represent ten through fifteen). You could use A for ten or maybe you want to use X (like roman numeral ten).
5037 = 248 = 3059
Not in a way that would be generally understood. However, it is possible. An 8-digit number in base 10 can be represented by a 5-digit number in base 32. For example, extending the scheme for labeling digits for base 32, VVVVV32 = 3355443110 Similarly, the 8-digit number 33333333 in base 4 is the 5-digit number 65535 in base 10
Perhaps we are thinking of the number 898? If so, then 8+9+8=25. But I am confused by the use of the plural "numbers", when there is only one largest. If I mistake the question, please rephrase it.
The decimal complement of the number 1 is 8. You can find the complement of any digit by subtracting it from the largest single digit value in the base that you're working in.
The greatest value a digit can have in base for is 3. Thus the largest three-digit number in base for would be 333. In base 10, this number is 3x16 + 3x4 + 3 = 63 Therefore 63 is the largest digit that would be three digits in base 4.
The largest 3-digit number in base 3 is 222. Its decimal equivalent is 26
The largest 4 digit number in base 8 is 77778 (= 409510).
666 - which in base 10 would be 294+42+8=344
It is 15.
999.
It is 15.
A three digit number cannot be divisible by a 5 digit number - in any base.
222

That depends on what base you are using. It could be 1
It depends upon the base of the number, but it is always one less than the base. For decimal numbers (base 10), our usual numbers, the largest digit that can be used in 10 - 1 = 9.
