Answer 1

The newer AGGREGATE function can help retrieve the appropriate values as well as passing their associated row numbers to an INDEX function to retrieve the names.

In E2:F2 as standard formulas,

=INDEX(B:B, AGGREGATE(15, 6, ROW(B$1:INDEX(B:B, MATCH(1E+99, C:C)))/(C$1:INDEX(C:C, MATCH(1E+99, C:C))=F2), COUNTIF(F$2:F2, F2)))
=AGGREGATE(14, 6, C$2:INDEX(C:C, MATCH(1E+99,C:C ))/ISNUMBER(MATCH(B$2:INDEX(B:B, MATCH(1E+99, C:C)), A$2:INDEX(A:A, MATCH("zzz", A:A)), 0)), ROW(1:1))

Fill down for four more rows.

        

Note that I've changed one of your values to demonstrate how duplicates are handled.
