Just share what I know:
CFP- A professional designation for those who engage in wealth management activities. In general, these practitioners are in private client, financial sales-related business, including Investment Advisors, Insurance Consultants, etc. They have general knowledge in personal taxation, insurance planning, retirement planning & estate planning. All these factors are needed to consider when FPs set up an investment plan for the clients. If the cases are special, they will refer to other specialists such as lawyer, tax accountants for consultations. (note: For CFP exam, different counrties have different exam syabullus due to the difference settings in lgal/tax structures.)
RFP- For some countries, having a CFP designation does not imply that an individual can conduct financial planning business. S/he has to register with the SEC, or similar goverence bodies. The SEC may also accept other financial planning desginations/qualifications from the applicants to register as RFP.
CMA- one of the professional accounting designations, specialising in using accounting for managerial decisions.
