This question is just my effort that I made by understanding the previous answers to my questions . I have a GHZ state $|000\rangle+|111\rangle$ (please ignore the normalizing constant). For teleportaion of these three qubits (GHZ state) I make use of a 8 qubit cluster channel. I do this in the following wayenter image description here

Can this be the extension of the case when we teleport a Bell state (two-qubit) using 4 qubits cluster state?

Can somebody just check on this circuit? What should be the outcome? Can anybody suggest a possible reference to read?

About checking. I do not quite understand why you can't check how the GHZ-state was teleported in the most ordinary ways: in addition to measuring the state immediately after teleportation, as well as by YYX, YXY, XYY, XXX measurements, you can inverse your GHZ-state and make sure that all 0 are obtained, e.g. like as for this with the most usual GHZ-state teleportation scheme: enter image description here I think that all listed checking methods (slightly customized) will work with other GHZ-state teleportation schemes, and in addition, the checking method by inversion will work with other desired states (of course, if you can comparing that was before creating state and that became after inversing of state).

About teleportation schemes of arbitrary qubit states via clusters states can see e.g. here.
