there are no bones in any kind of squid

Cartilage is the soft bonelike material that bends and provides structure and support to certain parts of the body, such as the nose, ears, and joints. It is more flexible than bone and can bend without breaking.
The squid gladius, also known as the pen, is a hard structure inside the squid's body that provides support and protection. It helps the squid maintain its shape and aids in movement by providing a structure for muscle attachment.
Squid are invertebrates; they have no spine.
The pen is a feather-shaped internal structure that supports the squid's mantle and serves as a site for muscle attachment. It is made of a chitin-like substance. It is the remnant of the squid's shell, so it is a vestigial structure.
Its beak helps the squid bite its food.
Ossification is bone formation. Calcification is the hardening of tissue into a bonelike structure. Not much, Thay are the same process with different names.

A squid's tentacles are homologous to the snail's foot.
The cuttle fish 'thing' is a rigid bonelike structure we call a cuttle bone commonly used in birdcages for birds to clean/hone their beaks.
Squids are invertebrates, therefore they do not have spines. An earlier form of the squid had a shell, but this is obviously no longer present. However, a structure called the pen remains, part of the old shell. This is what helps the squid to maintain its structure.
