If that person has more than $4,050 of reportable income in 2017, and they were not a full time student for at least one semester that started in the tax year, then no you can not claim them as a dependent on your tax return.

thank you for the answers but yes I provided more than half of his support and yes he
 lived with me for all of 2017 but he did make more than 4050?

can I claim him on my taxes

If he was not a student in 2017 and has more than $4,050 of earned income, you can't claim them on your tax return.

You can't claim if him if made more than $4,050 in 2017; whether or not he is a student is not relevant because you are not related to him.
