Man, as in male person, comes neither from Greek nor Latin, It has a Germanic root. Manu is more difficult without a context. There is an oceanic word manu which means bird. Manu is also a Hindi word for the first man, and derives from Sanskrit. (The Germanic languages and Sanskrit both derive from Indo-European). Manu, as short for Manuel is a Spanish/Portuguese name deriving from Latin and late Greek, but of course there are other similar names such as the Hebrew Emmanuel. The many English words beginning with manu- such as manual, derive from the Latin manus, meaning hand.
Actus is where English gets act from and it is Latin. It is the past perfect participle of ago, which means to move, set in motion, lead, excite, govern, do... Ago is one of the most common Latin words and has cognates in Greek, Sanskrit, and German.

Counter and product meaning in greek and latin words
Romance languages have their roots in Latin - and in Greek before that. Both Latin and Greek root words derive originally from Sanskrit - originating in the Indus Valley civilization. Thus, we now speak in terms of an Indo-European set of languages.
Yes, it's possible that Latin has a larger vocabulary than Greek. One reason is the borrowing of many words from the classical language of the ancient Greeks. But just for the record, the borrowing isn't one way. For example, the modern Greek names for the months of the year come from classical Latin.

Echo is the Roman name. It was transliterated (when you replace the greek sounds with their equivalent latin letters) from the Greek Ἠχώ. It's similar to how the Greek and Latin words for Apollo are the same, just that the Greek is spelled using the Greek alphabet. Sometimes the Romans didn't have original equivalents, so they just used the Greek name.
