number or number(s)

[summer rain]

Can I say:
They were few in number or number(s) ( referring to a group of people)

And which is more appropriate?
sun rays
or
sun beams?

I know I ask alot of questions but:
can I say enormous numbers of people?
Thank You,:n00b:

The people of Littleville may be few in number but they made their presence known at the county fair, taking home both Blue Ribbon for Best Apple Pie, and Blue Ribbon for Champion Pig.

The Boy Scout groups in Smallstate may be few in numbers, yet they hold their own Jambouree every year.

So, I can use few in number or numbers with 'the people' and 'groups' as long as I'm referring to a big group of people.
