Any one of vs Any of

Hi,

I was having a conversation with a friend of mine, who happens to be a native speaker of English. We were talking about the best footballers who don't play in England, and he said:

"If any of them goes to the English league, he will end up winning the league"

I understand that "any of them" can be interpreted as:

1)If any of them go to the English league, they will end up winning it. (If two or more of them go the league)

2)If any one of them goes to the English league, he will end up winning it. (this is what he meant)

But my question is: Is it formal to use a singular verb after "any of"?

If so, the interrogative form seems very confusing to me, specially when we use the auxiliary verbs "does" and "do".

For example:

1) Do any of you have jobs? (Implies that many of them have jobs)
2) Doesn't any of you have jobs? (sounds wrong since we can't use "doesn't" to refer to many people) (Implies that many of them have jobs) .

3) Does any one of you have a job? (Implies that only one person has a job)
4) Doesn't any of you have a job? (sounds wrong, but we can use "any of" to refer to a single individual) (Implies that only one person has a job)

Another example:

1)Has any one of you seen her?
2)Has any of you seen her?
3)Have any of you seen her?

Also, Is it idiomatic to use "any one of" to talk about inanimate objects and Ideas? For instance:

I suggested a couple of ideas the other night, and I am wondering whether any one of them made any sense to you.

Thanks for your time .
