Cap gain exemption for 2 property

Dear Expert 

There is case where A person named Ram who purchased a property of INR 42.5 lac price in 2020 and property is proposed to sell now of INR 1.04 cr

Out of this 1.04 Crore , 80 lakh will be used to purchase residential property. Whether there will be any capital gain here ?

2nd question whether new property purchased will be on the name of Ram or he can purchase the new property in joint ownership with his mother or wife?

Regards
