Yes, they are Sixth rangers as confirmed by the new version of Super Hero Getter as featured in the ending of Zyuohger episodes 28 and 29. If you watch those endings, you will notice that only core rangers are shown. When they get to the Go-Busters, you only see Red Buster, Blue Buster, and Yellow Buster thus confirming them as a team of 3 with 2 Sixth Rangers.
