After looking at this pic for a while, I feel not only like some one cut each person out of a magazine with safey sissors, but it seems like they chose the must UNFLATERING picture that they could find for many of the the girls...
Yurina's name is 友理奈. It is written in the Kana syllabary as ゆりな and in rōmaji as Yurina. However, though the り character is romanized as ri, it is just an approximation and depending on usage, it is pronounced as ri or li. In her self-introductions she always sounds like she says Yurina to me, but the difference might be too subtle for my western ears.
