You seem to be having trouble figuring out which word is the noun that needs to be the plural. Which thing do you have more of - twenty, year, or old? Twenty years is the modifier for old. You have two twenty year olds.
According to the Child Labor Coalition, 45% of the 18-year-olds in the United States are employed at least part-time.
The plural form of "old" is "olds." For example: "The olds in our family reunite every year."
There isn't a suffix for ten because there is no base/ root word.
