During the current year, Jen $($age $66)$ furnished more than $50\%$ of the support of the following persons:

$$Jen$$s current husband who lives with her and has no income.$$ He is not a dependent to any other taxpayer.$$ He will file a separate return this year if he files a tax return at all.$$Jen$$s stepson $($age $18)$ who lives with her and earns $$6,000$ as a dance instructor. He dropped out of school a year ago.$$Jen$$s ex$-$husband who does not live with her. The divorce occurred two years ago. He is unemployed the entire year.$$Jen$$s$$ brother$-$in$-$law who does not live with her and earned only $$3,000$ of taxable income for the year.$$

Presuming all other dependency tests are met, on her$$separately filed$$tax return how many of the$$above$-$listed individual$$qualify as$$a$$dependent$$to Jen?
