I would use a linked list (or any equivalent present in VB.NET) to store a struct with the pairs of values and suffixes.
Then after each entry I would count the values that are equal than the one you've entered (so this should be done in the change event of the editbox).
It all depends on what you want to do in terms of the suffixes, I would try to use the ascii table to increment the suffix automatically and if you are overflowing the "z" char due to an amount of z+# of values equal than the last one entered, then I would start adding another ascii start "a".

Using ascii makes it easy to change letters by calculus.

Control the overflow and then you are done...

This is not code but a bunch of ideas that could help you.

Good luck.
