"that afternoon"
Quien es (aquella)? (If 'she' is present/visible ('over there') Quien es ella? (If, e.g, asking in response to a name being mentioned)
'that one' is 'eso/esa' if it's near, 'aquel(lo)/aquella' if it's 'that one over there' The 'o' or 'a' ending depends on the gender (masculine or feminine) of the word describing 'that' - so 'aquel hombre' (that man over there); 'esa manzana' (that apple)
