The first expression will not work because you haven't escaped special characters.
The second one should work and it actually does work. Here's an example of usage:

pawn Code:

new 
    RegEx:regex_name,
    string[30]
;
    
public OnGameModeInit()
{
    regex_name = regex_build("^[A-z0-9@=_\\[\\]\\.\\(\\)\\$]{3,24}$"); // Corrected a little bit; your is still valid though
    
    // --------------------------------------------------
    
    format(string, sizeof string, "[TAG]_Player@Name=$"); // A valid player name
    
    if (regex_match_exid(string, regex_name))
        print("Matches");
    else
        print("Doesn't match");
        
    // --------------------------------------------------
        
    format(string, sizeof string, "[TAG]_Player@Name=$!"); // An exclamation mark added at the end (invalid character)
    
    if (regex_match_exid(string, regex_name))
        print("Matches");
    else
        print("Doesn't match");
        
    // --------------------------------------------------
        
    format(string, sizeof string, "$_Player@Name=Player@Name"); // 25 characters long name (too long)
    
    if (regex_match_exid(string, regex_name))
        print("Matches");
    else
        print("Doesn't match");
    

    return 1;
}

Output:

Code:

Matches
Doesn't match
Doesn't match

Here's a useful page where you can test your expressions. When using them in PAWN, you just have to double-escape characters, using 2 backslashes instead of 1: http://gskinner.com/RegExr/
