Hi Cheryl,
Both of your Ficus trees look healthy so you have taken good care of them. These trees can be sculpted to almost any shape or size that you want. The new one the left in the photo you posted has an unusual and interesting shape with foliage growth at the bottom and the top with bare stems in between - almost topiary-like. If you like that, then leave it as is. However, if you want a more traditional "standard" form, then I suggest you prune off some or all of the stems that have bare stems above the lower foliage growth. This will shorten the tree (temporarily), but produce more compact and uniform growth.
There is no "right way" to do this and pruning will not effect the overall health of your trees. Ficus trees respond remarkably well to pruning and challenge you to prune them to get them in the form that YOU prefer. Just remember that new growth will emerge just below the pruning cuts and grow outward from there. So just prune back any stem to a point where you would like to see new growth come in.
Be bold! Experiment and watch how the stems grow after they are pruned. Once you overcome your initial fears of pruning, it can be quote addictive! Today, I got to prune a doctor's 30 year old Ficus tree that had not been pruned in many years. It took me about 10 minutes and he and his wife were thrilled when I was done. Trust me, this is not rocket science and anyone can do it, although you probably won't get paid as much as I did!!
