For loop Group Positions 1-5 and check Position 6 & 7

Question

I'm fairly new to programming and I had a hard time coming up with a title for my question. Let me try to explain it a bit better:

I have a for loop that iterates through a list of strings

for (int i = 0; i < StringList.Count; i++)
{               

}

The strings have a general pattern: The list starts with:

1. String1
2. String2
3. String3
4. String4
5. String5

Then there is a possibility of StringT and StringB occuring randomly. After either string5 or the possible combinations of StringT or StringB occuring it goes back to a string1-5 and starts all over again. (Strings 1-5 are all slightly different but similar enough for filtering purposes). StringT and StringB both have identifying "features" I couldcheck in a if-statement

My Goal is:

Add the first 5 Strings to a TempString and check the possibillity of StringT or StringB being there. If they are there, add them to the TempString too. After That I'm adding the temp string to a list so list[0] would consist of (string1, string2, string3, string 4, string 5 and MAYBE StringT and or StringB)

Repeat the process after that until the loop is finished.

I tried it with a foreach loop and I tried solutions similar to this question: how to loop over generic List<T> and group per 3 items but none of them worked with the possibillity of random strings being there (at least for me)

You can check the possibility of specific strings in a group of the list as below:

bool StringListEnded = false;    
            var resultGroup = new Dictionary<List<string>,bool>();
            foreach(List<string> list in StringListGroup){
                    bool StringTFound = false;
                    bool StringBFound = false;
                    foreach (string item in list)
                    {               
                       if(item == "someStringT")
                       {
                           StringTFound = true;
                       }
                       if(item == "someStringB")
                       {
                          StringBFound = true;
                       }
                    }
        //here you can save values in the dictionary against each list from the group and the possibility of occurring specific string using both flags for stringB and stringT
    if(StringTFound || StringBFound){
       resultGroup.Add(list,true);
    }
                }
