Regular expressions - range.

[Loli-Kyn]

Briefly:
I want a particular translation to apply to a particular number

Detail:
Almost every word can have a plural applied to it. This changes the ending. There are usually two variants “Day”, “Days”. In English, usually only an “S” is added at the end of the word. (I'm not very good at English and I don't know all the subtleties yet).
But in Russian there can be several endings depending on the dependent word. “1 день” “2 дня” ”5 дней”
What I want to do:
Let's say in regular expressions there are digits from 1 to 20. I want to make a range of digits to which one of the given translations will be applied.

For example
The translation “A” will be applied to digit 1.
To digits from 2→4 the translation “B” will be applied.
To digits 5→20 the translation “D”.
“А” = 1
デッキあと{{A}}枚必要 同カード{{B}}枚まで=We need another {{A}} card. Stack of cards {{B}}
“В” = 2→4
デッキあと{{A}}枚必要 同カード{{B}}枚まで=Want more {{A}} cardS. Stack of cards {{B}}
“Д” = 5→20
デッキあと{{A}}枚必要 同カード{{B}}枚まで=Need more {{A}} cardS. Stack of cards {{B}}

{{A}} and {{B}} is an included regular expression to the numbers so as not to duplicate the translation. You already know that.

I will duplicate the examples in Russian so that you can notice the difference in the endings.
"А" = 1
デッキあと{{A}}枚必要 同カード{{B}}枚まで=Нужно еще {{A}} картА. Стак карт {{B}}
"В" = 2→4
デッキあと{{A}}枚必要 同カード{{B}}枚まで=Нужно еще {{A}} картЫ. Стак карт {{B}}
"Д" = 5→20
デッキあと{{A}}枚必要 同カード{{B}}枚まで=Нужно еще {{A}} карт. Стак карт {{B}}

Those are substitutions, not regular expressions.
Make 3 regexes, the last one is
r:"^デッキあと([5-9]|1[0-9]|20)枚必要 同カード(\d+)枚まで$"=Need more $1 cards. Stack of cards $2.

You might need to use \\ instead of \. idk

So if I want to apply this to all three options it would look like this?

"А"
r:"^デッキあと([1]|1[0-9]|20)枚必要 同カード(\d+)枚まで$"=Нужна ещё $1 карта. Стак карт $2.`

"B"
r:"^デッキあと([2-4]|1[0-9]|20)枚必要 同カード(\d+)枚まで$"=Нужно ещё $1 карты. Стак карт $2.`

"D"
r:"^デッキあと([5-9]|1[0-9]|20)枚必要 同カード(\d+)枚まで$"=Нужно ещё $1 карт. Стак карт $2.`

"А"
r:"^デッキあと1枚必要 同カード(\d+)枚まで$"=Нужна ещё 1 карта. Стак карт $1.

"B"
r:"^デッキあと([2-4])枚必要 同カード(\d+)枚まで$"=Нужно ещё $1 карты. Стак карт $2.
There are several sites to test and learn regex online. XuA uses NET version.

Thanks for your help.
I don't understand how to use regular expression validation sites.
