This is a good explanation of number, numeral, and digit. https://www.mathsisfun.com/numbers/numbers-numerals-digits.html In my experience, "figure" tends to be a number that was the result of some calculation, for example: "He is earning a six figure salary." (Meaning he makes $100,000 or more) OR "I balanced the budget. Could you check these figures for me, please?"

The meanings will differ with context numeral = a single written number like "1" or "4" not "23". Eg Germans write the numerals 1 and 7 differently to the English. The Roman numeral for 4 is IV. MMXX is 2020 in Roman numerals. number = a quantity, 0, 1, 45, 3E8, pi, -47, Used for many things at different times. Can be used to "numeral" or ""digit" sometimes. eg pi is an irrational number I can't read your writing. This number is twenty something? What's the second number/numeral/digit? digit - usually a single character of a number. eg The first digit of pi is 3. Clocks usually have four digits, for hours and minutes or six digits if they include seconds. figure - Often used for digit. Sometimes used for number, but I suspect less often by a long way. eg What's this figure here in this long number? I can't read your writing. pi squared to two significant figures is 10. "figure" and "figure out" are also verbs meaning something about working things out or your believe in something. eg I figure it is too far to walk to town. I can't figure this out. Also means image, picture or course.

Hello, Azeh Achou. Thank you.

A number is the idea and numeral is the representation. A numeral is a symbol or name that stands for a number. Examples: 3, 49 and twelve are all numerals. So the number is an idea, the numeral is how we write it. A figure can be any number. A digit would have to be one of the individual symbols used in writing a number.
