A dependent had ITIN in 2015-2017. In 2018 he has received an SSN. Is it fine to submit 2017 taxes using his old ITIN, or new SSN should be used?

Use the new Social Security Number. Once a Social Security Number has been issued, the Social Security Administration notifies the IRS and that is the number they want you to use.
