Is there a way to insert values into an arraylist and assign them with a string as key/index?
I tried:
arrayList.Insert("abc", "value123")

First, there is no need to use an ArrayList anymore. Use a typed List(Of T) to avoid that you always have to cast the objects which is also more error-prone.
In this case it seems that you actually need a Dictionary(Of String, String):
Dim dict As New Dictionary(Of String, String)
dict.Add("abc", "value123")
Now you can access it by key very fast:
Dim value As String = dict("abc") ' exception if it doesnt contain this key '
Note that the keys must be unique and that you can use TryGetValue or ContainsKey to check whether or not it contains the key to avoid the exception.

What you want is a StringDictionary
Dim myCol As New StringDictionary()
myCol.Add("red", "rojo")
