Plastic fixings , used here and on other for other fixings such as engine undertrays, are quite prone to breaking on removal. There is a fair chance you will break at least one.
Its a good idea to obtain some replacements of the correct type before starting the job ,rather than have the car unusable, or not fully secured ,until you can get some. Sods law if you have replacements you wont break any, but its not a bad idea fitting some new ones rather than reusing old mangled ones.
Unfortunately genuine Honda replacments may be quite expensive for what they are but you can probably find compatible aftermarket ones much cheaper.
