They could be hand sewing needles, but it would be great if there were some machine needles in there as well.
Actually the ruffler and tucker are a little different from later ones. I see you have an underbraider. I think those are neat. I tried some metallic soutache braid in one. I don't recommend using metallic soutache, but it does work well with other soutache. It looks like you have several hemmers and a binder. You also have a "shirring plate" that works with the ruffler.
