You are likely to only ever use the S, T, C and V shapes in general hobby lathe work, the W shape is also very useful,

This excludes threading and other forming tools such as radius groove and dovetail O-ring inserts, face grooving, parting and internal back chamfer tools.

The CN (80 Deg. diamond) tools are very robust, they have a very shallow angle rather then a sharp point such as a 60 Deg, triangle, they will face and turn unlike a triangle, they are negative and require a stout machine, part and setup. CCMT are positive and are an excellent choice when faced with a part, machine or setup prone to chatter.
