2,4,8 (1 and 16 are divisors too, but the number and 1 are always divisors)
Sum of divisors = 91.
12 has six divisors.
Here are all nine of 100's divisors: 1, 2, 4, 5, 10, 20, 25, 50, 100.

lets see...prime factorization of 100, 2,2,5,5 so divisors are 2,4,10,20,25,50 so the sum is 111 unless you want to include 1 and 100 then the sum is 212
Because the sum of its proper divisors is greater than 100.
Yes.
