5 more to do but I cannot parse them, so explanations as to how you reached the answer please.
A) Bit, through it, a hole (4) I?T? Tempted to put IOTA (bit) but why is a hole (AO) written backwards? Doubt if that made sense!
B) Sweetheart showing what used to be easy (4) ?T?E
C) Fire on border with elimination of Kazakh leader and chief (6) ?A?H??
D) Sorcerer finally heading into West? ??G? The first letter of this clue is also the last letter of "C"
E) Having got to know paid off (3) M?T. Only one vowel to find and I still can't parse it.
