For starters, I'd get some light weight sandpaper in 220 grit or something and take the irons out of them and then "plane" the bottoms of each to match the others on the sandpaper. as in, stick one upside down in a vise and use the other with sandpaper wrapped around tightly to sand the one in the vise, back and forth until they match.

That's assuming they're close in profile and the round is in pretty good shape.

Then, you can get an initial grind on the edge of the iron to match the sole by putting the iron in the plane and dragging the plane backwards until you've matched the profile of the sole with a flat across the edge of the iron. Take off no more than you need to while doing this, because grinding the profile with a coarse stone, grinder (whatever you have that will work) or coarse sandpaper wrapped on a dowel isn't easy work.

You can do a lot of the work grinding the bevel again by putting sandpaper on the opposite plane and holding the grind angle shallower than the plane bed, but some finish work has to be done by hand.

Larry williams advises using a cone in a rotary tool, and you can do that, but it's not necessary and it's easy to run over the corners on an iron doing that. Slow and steady wins the race in this case. You don't need perfect results, just "really good" results.

Once everything is cleaned up (back flattening before or after, doesn't matter -I'd do before) you install the iron and set it like any other wooden plane (a tiny amount of iron projection even across the sole), and sharpening isn't that frequent because you'll do most of your work with these planes after something simpler has removed as much waste as possible.
