I don't know what language you use but you can leave a comment and I would gladly update my answer for you and help. Edit: The OP specified javascript in the comments below.

@\[\w+:(\d+)\]

The result for each match is in capture group 1

You can check your input and regex at regex.com

var s = "@[Anonymous:2] abccdef, @[Sales:5]"
var r = /@\[\w+:(\d+)\]/g
var m = r.exec(s)
var a = []

while (m != null) {
  a.push(Number(m[1]))
  m = r.exec(s)
}

console.log(a)

@\[\w+:(\d+)\] performs slightly better and also captures the whole number (your current regex will only capture the last digit of a two or more digit number)

@ctwheels, thanx, check it now, you can run it here, it is only code snippet to help debugging his results

@msoliman I've simplified your Javascript and regex pattern (you don't need to escape everything in regex, plus the + was not in the capture group - whilst it should). Notice that SO has the snippet functionality and also includes a builtin display for the console.

@ctwheels thanx, appreciated

@TrầnQuốcVũ you can use [^:\]]+ assuming only one colon and right square bracket is possible within the []
