Yes under today's rules governing the Roman numeral system XCIX is 99 But during the Roman era the equivalent of 99 was probably IC (100-1 = 99)
ICIX is not used; if it were that is 99 (IC) +9 (IX) = 108 which is not a 2 digit number 99 is the maximum two digit number; in Roman Numerals, that is XCIX
The number 10 has a roman numeral of X. The number 50 has a roman numeral of L. These are the only 2 digit numbers with a single value.

The Roman numeral for 10 is X
The number 9 is the greatest one-digit number.
2 digit number
A decimal number has a base of 10, meaning that from the least significant to the most significant digit in a number the value of the digit increases by a factor of 10. Thus the least significant digit has a value of the digit multiplied by 10 raised to power 0, the next digit to the left (the tens digit) has a value of the digit multiplied by 10 raised to power 1, and so on. If you are considering decimal numbers, then the first digit to the right of the decimal point has a place value of 10 raised to power -1, the next digit to the right has a place value of 10 raised to power -2 and so on. In decimal system (unlike the Roman Numerals) the length of the number also signifies the magnitude of the number and there is a place value for each digit (again unlike the Roman Numerals).
The units digit of a two digit number exceeds twice the tens digit by 1. Find the number if the sum of its digits is 10.
The greatest value two digit number in Roman numerals would be [MM] with a horizontal bar placed above it, which would represent the number 2 Billion. In generally used Roman numerals MM represents 2000.
