Can a Yongnuo YN-622C trigger a YN-600EX-RT II, or do I need an RT transmitter?

I currently use a Yongnuo YN-622C system with a YN-565EX III. I’m considering adding two Yongnuo YN-600EX-RT II flashes and want to know if they can be triggered directly by a YN-622C on the camera, while also using my existing YN-565EX III in the same setup. If not, do I need an RT-compatible transmitter such as a YN-E3-RT II, and how could I include the YN-565EX III alongside the RT flashes?

Can I trigger the Yongnuo YN-600EX RT Il with the YN-622C?
No.
The YN-600EX RT II is more or less a (more capable in some ways) clone of Canon's 600EX-RT. It uses the Canon radio protocol.
Yongnuo developed the YN-622 radio protocol at a time before Canon had a radio protocol. At that time all of Canon's wireless flash system used optical communication which communicates via very short pulses of light.
Though both systems use the same radio frequencies in the 2.4GHz band (as do many other wireless radio devices, both camera related and not camera related), they speak different "languages" to communicate the same information.
Would I be able to do that or would I need to get a different radio, like a YN-E3-RT II? If so, how could I fit my the YN-565EX III C within that setup?
You would need an RT capable receiver, such as the Yongnuo YNE3-RX attached to the hot foot of the YN-565EX III C. The flash should be set as if it were mounted directly on a camera, as the receiver will mimic the camera's hot shoe to the flash.

No. The YN-622C system and the YN-600EX-RT II’s built-in radio use different wireless protocols, so a YN-622C cannot directly trigger a YN-600EX-RT II via its internal radio.
If you want to control the YN-600EX-RT II flashes by radio, you need an RT-compatible transmitter such as a YN-E3-RT II or another compatible RT transmitter.
If you want to keep using a YN-622C transmitter on-camera, the YN-600EX-RT II units would each need their own YN-622C transceiver attached to the flash foot. In that case, you would not be using their built-in RT radio.
To include the YN-565EX III with an RT-based setup, it won’t join the RT system through its built-in radio. You’d need to trigger it separately, for example by attaching a compatible receiver/transceiver to it, or use another non-RT triggering method.
In short: YN-622 and Canon/Yongnuo RT are not directly compatible.
