The steel technology is probably beyond them, given the processing steps they can never derive from sampling the finished article. Iron & steel would have been a reach.
Ship-building, on the other hand, is right there before them. They had wood, they could likely have reverse engineered ropes & canvas sails using native hemp. They could have gotten by, scaled down, with wood, sail, tar, dowels & stone.
Artillery/musketry, again iron dependent, would have been tough. If they had managed to secure a smithy from the european crew, all the iron/steel technology transfer might get a crucial kick-start.
Metal-working would clearly be the critical path. They would also still have to confront the epidemics from the Europeans which did inevitably decimate their population.
