Most of these would not count as separate branches, certainly reserves and development couldn't be separate, and paramilitary organisation don't count in this case.
According to wikipedia Madagascar has "Development" as a separate branch, thus my inspiration for it. The idea in my mind was that it would be similar to the emergency response but with more sustained emphasis, in hypothetical country with the military highly involved in civilian affairs. Perhaps as part of said highly militarized country they use draftees for labor on various things and "Development" manages that.
Reserves are also not incompatible as a branch; it could constitute the branch of the military responsible for training conscripts and reserve. In hypothetical country, with an incredibly fragmented array of services, it could make sense to have yet another service for just training, to prevent excessive specialization and the problems of the relatively small size of many of the branches, and fitting in with the idea of the "Medical Service and Support Services", the idea of having administration and rear area action separated from front line services. If not under this system, hypothetical country could be very decentralized, and reserves as they exist might be under the command of states and other administrative sub-units making it up, thus making a centralized organization responsible for their command and utilization practical and desirable.
Also even if the OP didn't state that paramilitary units counted specifically, it is generally acknowledged that they can exist, a la the Gendarmerie Nationale for France or the Carabinieri.
