No, it is the empty set. Then the set containing only the number 0 (Peano's first axiom).
Numbers never end, therefore there is no smallest number only smaller than the last.But it depends on the number system that you are defining, and what you mean by smallest - is is smallest magnitude, or a number which everything else is greater than it. For example, if you are dealing with natural numbers [counting numbers: 1,2,3...], then there is a smallest number, which is 1. If you're dealing with integers, and you mean smallest magnitude, then zero would be your number, but all of the negative integers are less than zero. What if your system is 8-bit signed binary numbers (so the range is -128 to +127). So you need to be specific about what you are looking for.

In mathematics, 2 is the smallest prime number and the only even prime number. It serves as the foundation for various number systems and is the first number in the set of natural numbers greater than 1. Additionally, it is the base of the binary number system, which underpins digital computing.

The smallest natural satellite in the solar system is Deimos, one of the two moons of Mars. Deimos has a mean radius of about 6.2 kilometers.
They are the numbers that are used for counting objects. They form the basis of the number system. Even so, why "natural", and not primary (like in colours) I don't know.
They are used for counting things. Also, they form the basis for the rest of the number system: the integers, rational numbers, irrational numbers, complex numbers, quaternioins.
In the number system , there are decimal numbers, fractions,rational numbers , irrational numbers , negative and positive numbers.-0.567 on the number system is negative number.
The Dedekind-Peano axioms form the basis for the axiomatic system of numbers. According to the first axiom, zero is a natural number. That suggests that the question refers to some alternative, non-standard definition of natural numbers.
Almost all numbers that we use in daily life are decimal numbers. The place value of each digit is ten times the place value of the digit to its right. And that is all that is required of decimal numbers. A decimal point is not necessary.
There is no smallest number and no biggest number. Given any big number, however big, it is always possible to find one that is bigger (and the same with the smallest).
