‘-Top photo might be a type of sedge (Cyperus)? -The last two photos appear to be the same? Without flowers & other details, closeup of ligule, culm, node, roots, etc…it will be hard to tell more. You could let them bloom and give us an update with other details mentioned above to help with the ID. But it’s probably would be faster if you could take a few samples roots & all to the local Agriculture Extension. For now check out species of Cyperus in the first included link.
