There isn’t any way, using a query, to associate rows, unless you do 2 or more queries.
First you need to get the posts that have one of them, for example, get all the posts with “T5”. Then you need to get the row index and then do another query for the other field using this row index. Also, you cannot do this second query on more than a single index, so if “T5” does not occupy the same row index on all posts you’ll need to do multiple queries here.
Basically, what you’re trying to do is pretty much impossible using repeaters.
