"Dadas" is a word that can have multiple meanings depending on the context in which it's used. However, if we consider it as a colloquial term that refers to a father or dad, some synonyms for it could be "papa," "pops," "daddy," "pa," "old man," "sire," or "fatherly figure." Each of these synonyms has a slightly different tone and connotation, but all convey the same paternal relationship. Additionally, if "Dadas" is used as a plural noun to denote a group of fathers, then "dads," "fathers," "papas," or "paterfamilias" could be alternative terms. It's important to choose the right synonym that suits the intended meaning and tone of the communication.
