Come to the bus stop 5 minutes prior to the scheduled time.
Make sure you are in time for the bus. Allow at least five minutes just in case the bus comes earlier.
Come to the bus stopの部分は、pleaseを添えるなど、状況に応じて基本英語で習う依頼表現に入れ替えれば良いです。prior to はbeforeでもいいですが、ここではフォーマルに表現してみました。
2番目の例は、口頭で伝える感じにしてみました。「バスに間に合うようにしてください。少なくとも５分は余裕を持ってください。早めに来ることがありますから。」という感じです。
参考になれば幸いです。
