Yes, think PTSD, post traumatic stress disorder.
No, "post procedure" is typically not hyphenated in standard usage. It is used as two separate words to describe something that occurs after a procedure. However, in some specific contexts or style guides, it may be hyphenated as "post-procedure" when used as a compound adjective before a noun (e.g., post-procedure care). Always check the relevant style guide for specific usage.
yes
Ordinarily it is spelled as the hyphenated form "post-secondary."
