Yes. All of these fall into the Phylum Chordata. They all contain a notochord, dorsal hollow nerve cord, pharygenal slits, and a postanal tail, which makes a chordate a chordate. Although the animal may not contain all four of these at a certain point of their lives, no matter what stage of life(adult or embryo) if they contain these they are considered chordates. basically the answer is yes.

Agnaths(Cyclostomes) or jaw-less fish and Chondrichthyes (Bony fish) and amphibians and reptiles and birds and mammals all belong to Phylum: Chordata.
The non-chordates would be:
Prostists (bacteria),
Porifera (sponges),
Cnidaria or Coelenterata(sea-anemones and jelly-fish)
Platyhelminthes (tape-worms)
Nematodes (round-worms)
Annelids (earth-worms)
Arthropods (insects including crustaceans-crabs, shrimp)
Mollusks (snail, clam, octopus)
Echinoderms (star-fish, sea-urchin)
Algae (kelps included)
Fungi (mushrooms included) and
Plants
are non-chordates.
