No. Numbers are like words, and digits are like letters. A single numeric character is a digit. A single digit or character stands for a number of that value, just as you can have a one-letter word.
There are only ten digits in all: 0 1 2 3 4 5 6 7 8 9. They can be arranged in any combination and quantity, and the result is a number--a grouping of symbols that represents a value. 2, 79, 8407, and 91827365149307 are all numbers, and each of them is made up of digits. Only the first of those is both a number and a digit.

This cannot be answered. This will have to be written to where it can be understood.
I assume you mean how many 4-digit numbers can be made from a set such as {A,A, B, C} where A, B and C are single digits. There are 12 such numbers.
There are 900 of them.
If I understand the question correctly, the digits 1, 2, 3, 4 and 5 appear the same number of times.

When multiplying numbers with significant digits, count the total number of significant digits in each number being multiplied. The result should have the same number of significant digits as the number with the fewest significant digits. Round the final answer to that number of significant digits.
They are both 4554454 with the same digits in the same order and position so they are the same number.
