The guest in this case is already entitled to lounge access, the term guesting is wrong as then only Gold and Plats would be suitable and try picking those out of a line-up (ok, maybe not that hard, but still). The OP just needs to appear to be accompanied by an adult, whether they're on the same flight should be irrelevant.
A father and son might be flying ex DXB to different destinations at similar times, surely then the son could visit the lounge with the father if both are eligible, regardless of any status.
