"They're arriving!" is one English equivalent of the Italian word Arrivano!
Specifically, the word is a verb in the formal second person plural (Loro, "you, you all") or the third person plural (loro, "they"). It is in the present indicative, which translates as "are arriving, arrive, do arrive". The pronunciation will be "ar-REE-va-no" in Italian.
There is no such Spanish word as "arriva". There are two possibilities as to the source of the confusion.
Perhaps you mean, "arriba", which is the Spanish word for "above". Because of the "rr", it was used in Speedy Gonzalez Cartoons as "arriba arriba!" incorrectly to mean "faster, faster". This meaning has stuck in a more slang or joking context.
Perhaps you mean the Italian word "arriva" or French word "arriva" which mean "he arrives" and "he arrived" respectively.
