That's tough spacing. They were capable of getting the cut right. They should do it over.

Electric lid or plumbing? What are these covering? Maybe one large rectangular box is better?

These pavers may not survive these cuts. Pull out all 4 pavers, pour a square piece of concrete around these round cleanouts. If can be done to the edges of the next piece or smaller and fill in with rectangles. Option if this is just a paver add to existing, drop the boxes below the pavers. It will be fun finding them later.
