a- I've never been to Malaysia
.b- Ahmed was here earlier but he's left now
.c- Have you ever had a serious accident? No, I haven’t
?d- Has your sister ever played football
.e- Has he ever been to the USA? Yes, he has

The sentences are fine except you need a final period/full point.

They seem fine to me, except a,b,c and e need full stops at the end and d should have the ? at the end not at the beginning.
Also, as a general rule, you should have a comma before "but" ( b ).
