Animal Phyla Classification

I need some help classifying animal phyla, the document attachment has a table with nine images. The images are examples of nine different Animal phyla: Porifera, Cnidaria, Nematoda, Arthropoda, Platyhelminthes, Annelida, Mollusca, Echinodermata, and Chordata.

Using the Dichotomous Key determine the Class category as shown for each animal (picture), and write the Class names under the Classification Column on the table.
List in column 2, all of the dichotomous key steps chosen when using the key to arrive at the classification for each animal.

Also list the Phylum name for each animal picture in column one using the nine Phyla listed above. Once all the Class category for each animal using the Key has been identified, look up the correct Phylum category using a credible reference.
