I have an old coal burning fire place with an unlined 5 in flue. I want to put a small wood burning stove there and pipe up the flue. Is there a stove pipe small enough to fit? If so should I get a stove that pipes out the back? TIA

Without knowing the exact dimensions of the flue and info on any offsets etc there is absolutely no way for us to know. And you need a liner not stove pipe just fyi

If the flu opening is only 5 in you're going to be really tight on trying to get something in there. Maybe just to use the existing Hearth and go straight up through the ceiling with double wall and then Class A pipe.
 
Sounds like it may be pellet stove territory with a 3" liner.

Maybe a Jotul 602 would work. The actual flue collar is 5” or a bit less? Not sure if there is a liner that would work though?
 
After further inspection, I found the the narrow part of the flue is a smoke shelf. I was thinking I could either use my 4 1/2” side grinder with a masonry wheel on it to shave part of the shelf off or just break it off. The top course seems to be completely exposed. I assume the shelf no longer needed since I’ll be using a flex liner. Beyond the smoke shelf is an approximately 8” x 8” shot all the way up.

Nice, then an insulated 6" liner should work, allowing for standard wood stoves. You'd still need a rear exit one though, limiting the set from which to select again.
 
Awesome to hear you can run a standard stove with insulated liner. Now start on wood and look for fast seasoning types like ash, pine, silver maple, cherry those should be ready by next season. If you don't have sub 20% wood already look into bio bricks or other compressed sawdust logs.
