Help with Regular Expression cases

I have content with propietary scripting. This content is loaded into an editor (FCKeditor), but I want to create regular expressions to tell the editor to leave the source code alone for these areas (to avoid formatting and encoding).

Below are the cases I am trying to build regular expressions for. Can someone help with creating the regex to encapsulate the 6 cases below to tell my editor to leave them alone?

1) Multi line tags enclosed by using the [[ and ]] syntax.
Example 1: [[layout:header]]
Example 2: [[ConLib:MyOrderPage HandleFailedPayments="true"]]

2) Variables are indicated by a dollar sign, and may be enclosed in curly braces.
Example 1: $User.FirstName
Example 2: Hello $User.FirstName!

3) Variables are indicated by a dollar sign, and enclosed in curly braces.
Example 1: ${variable_name}
Example 2: some_text${variable_name}some_more_text

4) Any line that begins with a # pound sign is interpreted as a line of script.
Example:

#set ($counter = 1 && $other > 25)
Currencies provided by $Store.Name:<br />
#foreach($currency in $Store.Currencies)
$counter. $currency.Name<br />
#set ($counter = $counter + 1)
#end

5)  Single line comments are created by starting a line with a ## double pound sign.
Example: ## single line comment will not be output

6) Multi line comments can also be included, by using the #* and *# syntax.
Example:

#* This is a
comment that spans
multiple lines and will
not be displayed
*#
