All of the F-mount bodies (D6–D3400) will support the lenses you currently have without any problem. Your lenses (assuming they're DX lenses) can be used on the F-mount FX bodies (D6-D780), but will use the center 63%44% of the camera's sensor, because DX lenses (so-called 'crop lenses') project a smaller image circle than full-frame (FX) lenses. These FX bodies will automatically detect DX lenses and save appropriately cropped images; there's nothing you have to do when mounting the lenses, or in post-processing).
All of the Z cameras use the Nikon Z-mount. You need to use the Nikon F to Z adapter to use your existing lenses on a Z-mount camera. The same FX/DX considerations apply when using your lenses on a Z camera + F-to-Z adapter.
