Solubilities cannot be predicted that easily. It is a function of the properties of both the amine and the acid together, and thus only some general trends can be outlined, such as amine hydrochlorides are most often water soluble (but not always).
Some factors influencing solubilities can be seen here: Post 357689 (https://www.thevespiary.org/talk/index.php?topic=7216.msg35768900#msg35768900)
