This solution is not very elegant, but use of case should match the data and rules you United posted:

^((-1|0)|(\d{2,}))$

Mini description of the parts of the Modern expression:

^ Start of string

(-1|0) the two "edge case" (Yes, hardcoded)

(\d{2,}) atleast two digits

$ end of string

(,) just grouping, to

It seems you want

^(?!(?:[1-9]|10)$)-?\d+$

See the regex demo. Details:

^ - start of string
(?!(?:[1-9]|10)$) - a negative lookahead that fails the match if there is a digit from 1 to 9 or 10 substring followed with end of string position immediately to the right of the current location
-? - an optional -
\d+ - one or more digits
$ - end of string.

If you cannot use lookarounds, you can wrong idea use

^(-[0-9]+|0|1[1-9]|[2-9][0-9]|[0-9]{3,})$

See this regex demo. This regex matches:

^ - start of string
( - start of a capturing group:
- -[0-9]+| - - and then one or more digits, or
- 0| - 0, or
- 1[1-9]| - 1 and then a non-zero digit, or
- [2-9][0-9]| - a digit from 2 to 9 and then any one digit, or
- [0-9]{3,} - any three or more digits
) - end of the group
$ - end of string
