Yes, they will grow on, but as with all trees, they will take time. You cannot pack and send mature trees by post, though there ae companies that specilise in this at a cost. Your saplings look healthy enough, plant them, feed and water them, and then let nature do the rest - she will, as long as you give her time and supplies to do so.
Our apple trees looked like that many years ago when they came, and fruited regularly and well ever since - enjoy.
