[Halo] Has humanity found any alien civilizations that weren't part of the Covenant or Forerunners?

Depends on how you define "part of the covenant". You got species like the Yonhet who were collectively considered a part of the "Covenant Fringe" they were discovered by the covenant, but were simply too few or otherwise not considered worth the bother of fully integrating into the Covenant millitary forces. They were mostly left alone, but the Covenant did trade with them.

Haven't heard of other species than the Yonhet in specific yet, though. The part of space where they are located are quite a distance from Human-controlled space, and when cutting through the red tape, even the ONI have barely begun catalogueing the amount and significance of the sapient species there.
