Question

Is it OK when I say "I have a little request from you"? Is it commonly used?

Answer 1

I'm assuming you mean “a little request for you”, because it otherwise doesn't make much sense.

It is understandable, though quite informal. If I want to answer positively, I would typically reply “Yes, what do you want me to do?” or, if the context is more formal, “I'd be happy to help. What can I do?”.

Answer 2

"Can I ask a small favor of you?" Is a more commonly used phrase, that expresses the same meaning as a request.

Answer 3

If you have received a little request from someone, then saying something like

I have a little request from you, sat in my inbox. I won't be able to get to it until later, sorry.

is perfectly fine.
