seems to work fine Case 2 seems the opposite as case 3, so I don't think you can combine the Patterns.
For case 2, your Pattern could look like:
code :
Pattern pattern = Pattern.compile("(\\s|^)Hello(\\s|$)", Pattern.CASE_INSENSITIVE);
Pattern pattern = Pattern.compile("[\\$#@\\^&]Hello(\\s|$)", Pattern.CASE_INSENSITIVE);

around this issue I'm not certain of your full question, but you'll need to use a Regex escaper for conditions like this one. The $ is a special character. It would be \$ to actually search for a dollar sign. You should look up other special characters and be aware of them too, though C# regex escaper will do the tick.
EDIT Like this:
code :
string[] names = 
{
    "Jordan Ghassari",
    "James Cunningham",
    "Ghabriel Bercholee",
    "O^Brian",
    "Depto #345",
    "This is Ex$ample",
    "$amuel"
};

string searchFor = Console.ReadLine(); // Input
searchFor = @"(?:(?<=^|\s)(?=\S|$)|(?<=^|\S)(?=\s|$))" + Regex.Escape(searchFor); // searchFor is input value to look for

Regex regEx = new Regex(searchFor, RegexOptions.IgnoreCase);

List<string> matchedNames = new List<string>();
foreach(string name in names){
    if (regEx.IsMatch(name))
    {
        matchedNames.Add(name);
    }
}

foreach (string match in matchedNames) 
{
    Console.WriteLine(match);
}

hope this fix your issue Requirement is to find if the search string is present in the given string with below conditions. , You can apply all the assertions without alternation here:
code :
/(?<![a-z0-9])(?<!^[^a-z0-9])(?<!\s[^a-z0-9])abc/igm

Does that help As in the comment. You can use because the exclamation mark and equal sign are not part of word-character class you can simply test for those characters and match the word characters between them. check:https://regex101.com/r/qDrobh/4
For multiple words you can use: See:https://regex101.com/r/qDrobh/5
