The Polyspace custom rules use regular expressions to detect patterns, so you can go as far as regular expressions can take you. For instance, you can create a rule that variable identifiers must have the first letter capitalized. See a similar tutorial here: https://www.mathworks.com/help/codeprover/ug/create-a-custom-coding-rules-file.html
Use the custom rules here: https://www.mathworks.com/help/codeprover/ref/group-9-variables.html
Likewise, you can also enforce that a function name can consist of several parts separated by underscores only and each part must have the first letter capitalized. There are many sites such as https://regex101.com/ where you can build regular expressions on the fly and test your expressions.
However, some of the things you are asking will also require a dictionary that you can compare against. The dictionary should not only have English words but also acronyms (you might want to explicitly build the acronyms part of the dictionary). You cannot yet create such a dictionary with Polyspace and create a custom rule that compares against items from the dictionary.
