The things you should know are:
1. "Пять", "Двое", "Трое", "Четверо" ("collective" numerals) are more colloquial
2. "Collective" numerals are mostly used with masculine nouns or nouns of common gender + nouns like "kids". In actual speech it is sometimes used with feminine nouns, even though technically it's illiterate.
3. Same as in English, there are some plural-only nouns in Russian (like pants, scissors). You cannot use "два", "три", "четыре" with them when the sentence requires "Nominative" in that position, so use двое/трое/четверо. You can use "Пять" with them. The reason is, if the case is not oblique, два/три/четыре have noun in Genitive singular, and these nouns don't have singular. That becomes problematic with numbers like 22: you cannot say "22 pants" in Russian. There is, obviously, no number "двадцать двое", only "двадцать два" which doesn't work well with plural-only nouns. So in these rare cases you'll need to rephrase ("штаны, 22 штуки", like "pants, 22 pieces").
