There are a few abilities:

R2-D2-recover a shield token.

K-4 Security Droid-gain a target lock.

Lando-give somebody an action.

Night Beast-perform a free focus.

BB-8-technically this happens before the maneuver, but execute a barrel roll.

Are there any others?

It's not confirmed, but I'm guessing that the Targeting Astromech that comes with the T-70 Expansion probably does the same as the K4 Droid. The little snippets of wording you can make out look suspiciously like it.

Well... from a certain point of view, if you start the activation phase stressed... Kyle crew will give you a focus after you performed a green maneuver to clear the stress....
