I have been trying to find definite descriptions of these terms for a while and have had limited luck. From what I have cobbled together from the interwebs is this;
These are all long term fuel trim adaptations.
rkat is idle adaptation and should be at 0.
Fra is running adaptation and should be at 1.
Frau/frao are different load range for the running adaptation. Cannot find defined rpm or load ranges, but they should also be at 1.
Here's the best single website I have found about this.

In other words, your fuel trims are perfect!
