2-3 days is really too soon to tell. Right now they are adjusting to your tank and starting to set new roots. They all look very healthy right now, but don't get upset if you see some stress. Just let the new period ride out and make sure you've got the nutrients for them.
You should seperate any plantlets you can into several plants (especially seperate out the stems plants) and plant them an inch or so apart. This will help them to do better, not shade themselves out, and it gives you MORE PLANTS! Your tank will fill in much faster that way.
Dave is right that the time frame is not enough. Keep in mind, most all swords sold at lfs's are grown emersed, so you will lose those leaves over the next couple of weeks as the plants transition from emersed to submerged.
