Answer 1

do you know what "finite" means?

Any set whose elements can be counted ?

Answer 3

hmm no

Answer 4

some sets can be counted even if there is an infinite number of elements in them

Answer 5

but perhaps it would be easier to think of it that way, you can count them and at some point you would stop
for example, there are 26 letters in the alphabet, so if you counted them you would stop at 26

Answer 6

there are two more finite sets in your question
what do you think they are?

Answer 7

All natural numbers less than 100,000
All the world's population
