Question

my friend requested me to wait there till he renturned .​

Answer 1

if your question is to change the sentence into direct speech then your answer--

My friend said to me," please wait till I return "

Answer 2

My friend said to me, “Please wait here till I return.”

The given question is in indirect tense, but when it is reported directly, it will be within quotes.

So when it is reported it is an indirect quote and when it is told directly, it is within quotes with all the subject and predicates all occur in the same manner.
