They look good. Good growth all similar hight ect, good growing. Are they all from seed ?
If your source/sender is reliable and you can trust them and they use good methods of getting them to you, you should be fine. Live clones and snips have been getting moved about the globe for many many years. Be discrete with the send method as boader control and customs are tight on letting plants or parts of them especialy while still alive and not sterile in and out of boarders. Pests and plants ( eg like japaneese knot weed did) can cause alot of trouble when introduced to a stable eco system so they watch closley for plant material.
By the way what clones are you trying to get from there ?
