Finite, no.
This is called a discrete set (all points isolated) or a finite set. Finite sets are always discrete.
A finite set is a set that has numbers you can count. Its not like infinite with no end it has an end.
All of the natural numbers.
0 and negative integers are all whole numbers but they are not natural numbers.
Yes, that is true.
The whole number form an infinite set.The natural numbers less than 100000 form a finite set(either 99999 or 100000 members, depending on whether 0 is considered a natural number).The letter of the alphabet form a finite set (26 members for the English alphabet).The odd numbers form an infinite set.
Infinite.

The empty set is a finite set.

No, a finite set can be a set of anything - as long as it has a finite number of members.Some examples of finite sets are:the set of black chess pieces in a chess set (16 members)the set of all red 2010 cars made by Ford (unknown but finite number of members)the set of planets orbiting our sun (8 members)the set of numbers between 14 and 23 that are integer multiples of pi (3 members) {5*pi, 6*pi, 7*pi} The elements of this set are all irrational numbersthe set of marbles inside a pint jar (unknown but finite number of members)the set of bowling balls in a 2 liter soda bottle (0 members as a bowling ball is too big to fit in a 2 liter soda bottle)etc.
All of the natural numbers.
The set of your friends is finite. The set of counting numbers (part of which you will use to count your friends) is infinite.
0 and negative integers are all whole numbers but they are not natural numbers.
