DSI, DPI, composite, and both HDMIs can ALL be used at the same time on Pi5.
Do note that they are provided by different DRM/KMS devices, therefore they will have different /dev/fbN nodes for their framebuffer emulation. labwc will work quite happily rendering across all of them.
If you want to use them all outside of a window manager, then you'll need to address the appropriate devices.
(Earlier Pis were limited to 3 of those simultaneously, and with some other restrictions).
