Animals in the same class share more specific similarities than those in the same phylum, as class is a more refined classification that groups organisms with closer evolutionary relationships. For example, within the phylum Chordata, mammals (a class) have more in common with each other, such as characteristics like warm-bloodedness and mammary glands, than they would with reptiles or birds, which are also in Chordata but belong to different classes. Thus, comparing two animals in the same class is typically more relevant for understanding their similarities than comparing two animals in the same phylum.
Phylum: Chordata Class: Chondricthyes
Actually, the classification of animals goes from broad to specific, starting with kingdom and descending down to species. The hierarchy is: kingdom, phylum, class, order, family, genus, and species. So, animals with a spine would be classified in the kingdom Animalia, phylum Chordata, class Mammalia (for mammals), and so on, down to the specific species.
There is no longer any difference in the classification system of plants and animals. Before, it was that you would use the term division for classifying plants instead of phylum,used to classify animals. Now, phylum can be used to classify plants and animals.
The octopus belongs to the phylum, Mollusca. It shares this phylum with its brethren squid and mollusks. It is a cephalopod, the octopus; therefore, Cephalopoda would be its class. Hope this helps.
Two animals of the same class would have broader similarities compared to two animals of the same order. Animals of the same class share basic characteristics and evolutionary history, while animals of the same order share more specific traits and behaviors within a class.
They are not. Why would you that they are similar? They are not even in the same phylum.

Squidward would belong to the phylum Mollusca, along with other animals like squids and octopuses. This phylum includes soft-bodied animals with a muscular foot and a mantle that may secrete a shell.
Butterflies belong in the Phylum Arthropoda, Class Insecta, etc., whereas polar bears belong in Phylum Chordata, Class Mammalia. This means that butterflies, though animals, are not vertebrates nor are they mammals: they are invertebrates and thus insects.
Scientific classification (Linnaeus classification) is used in order to group similar animal together. It is done by finding common ancestors, and moving in order of specifics up the classification. Kingdom, Phylum, (Subphylum,) Class, Order, Family, Genus, Species. For example, animals with a very recent common ancestor may be from the same genus, while animals with a more distant common ancestor would be only from the same phylum.
A slug would go into the phylum mollusca, along with clams, octopi and squid.
Phylum Athropoda, ( The Arthropods) as they contain the insects of which there are 800 000 species and the insects are the most abundant animals on earth.
