Neither; the sums are equal.

Well, 25 twos is equal to 50. So 10 fives are equal equal to 25 twos.
you can make at least 25 sums
Infinitely many. 12+11, 13+10, 14+9, ... , 22+1, 23+0, 24+(-1), 25+(-2), ... and then you have sums with numbers to one decimal place (dp) such as 11.6+11.4, and so on. Not forgetting numbers to 2 dp, 3, dp, 4, dp, ... , infinitely many dp. But these are only sums of two numbers. There are sums of 3 numbers, 4 numbers, ... infinitely many.
Infinitely many. Infinitely many. Infinitely many. Infinitely many.
Well, 1 is equal to 1. 9 is equal to 9. So any number from 0 to 9. I do not think this is what is meant by the question. If you mean any number with more than one digit. There is no such number. Because 11 sums to 2. 19 sums to 10. 21 sums to 3. 29 sums to 11. 111 sums 3. 119 sums to 11. The sums do not grow as fast the increase of digits.
