As we arrived on the FBO ramp in Aircraft X; we were directed to park in a corner directly in front of a propeller Aircraft Y. While were closing up our aircraft; the pilot of the Aircraft Y approached my SIC (second in command) and asked if there was enough room for home to fit between our airplane and an Aircraft Z. The SIC told him there was not enough room and that he should wait. The line personnel told him they'd move our airplane so he had enough room to depart. As the line personnel start connecting our plane to the tug; the Aircraft Y pilot loaded his passengers and started his engine. Immediately after starting; he began taxing between Aircraft X and Aircraft Z. While moving; Aircraft Y was being rocked by the winds on the ramp causing his wing to move up and down. As he approached our aircraft; he maneuvered to place one of his wings over our wing and the other over the nose of Aircraft Z. The line personnel gave the Aircraft Y pilot thumbs up and never attempted to give the signal to stop movement. As his wing crossed over ours; the two wings were within a foot of each other; especially due Aircraft Y's wing rocking. They got so close that one line guy actually tried to keep the Aircraft Y's wing from striking our wing with his hand. Aircraft Y made it past both our aircraft and Aircraft Z without making contact; however; it was in very close proximity.
