Motta and Rinaudo are loans with options to buy. Rinaudo has an option at 4 mill, and Motta at 5 million.
Trarore, AFAIK is just a loan (cost us 500,000 E for the season long loan).
I highly doubt we'd take up the option to sign Motta and Rinaudo.
Pretty sure Rinaudo had an option to buy clause?
EDIT: Yep he does, 4 million euros apparently. Not that we'd buy him
