Thanks to Rovang's Power Rangers Unpatched Prop wise we don't know how many they had. But color-wise, let's say there was 10 (2 Blue, Red, Black, Yellow, Pink, Green, White, Gold and Purple)
Billy presents the gang with the five communicators; Blue, Red, Black, Yellow and Pink
Trini's communicator, first time we see the antanes, rare we see them again
Billy's blue communicator
Kim's pink communicator
Zack's black communicator
Tommy's green communicator, as a kid I thought the second thing was a microphone or headset, but I have no idea what it is now.
Adam's black communicator, we never saw the first trio during the power transfer out of suit so we didn't see them pass over the communicators.
Rocky's red communicator
Aisha's Yellow communicator
Kat's Pink Communicator
Tommy's red communicator
Rocky's Blue communicator
Tanya's Yellow communicator
Adam's green communicator
Jason's golden communicator with black stripes, other communicators are silver and just change stripes. This is the only one that was a different color.

Billy still wore his blue communicator, kinda hard to tell here. It is unknown if he took it with him when he went to Aquitar, most likely.

Carlos' Green Communicator
TJ's Red communicator
Justin's blue communicator, most likely Rocky gave him his because Rocky didn't wear one in the first ep of Turbo.
by Space, they made a different sound, like the one from the Astro Morphers which was like a worp. Anyway, this is the last season to have the communicators.
Carlos' Black Communicator
Andros' Red Communicator (rarely seen)
TJ's Blue communictor, hard to find a close-up pic; unknown if they took Justin's or just had Alpha make another one.
Karone's 'honorary power ranger' jumpsuit (looks like a janitor jumpsuit).
Notice the purple pyramid, like the color rnager-color pyramids with lighting bolts. Instead of ranger-color coded bar, they are all purple and the communicator has purple stripes. We don't exactly see her wear the communicator.
Also... have you guys ever seen this???
Sweat suits just like the space suits, with the giant 'M' on the back, the pyramid with lighting bolt and ranger-color bars on the left and the 'planet' sign on the right. No badges on arms, just lines.
