Hard to say without actual live pics and you need reflector images too. I don't like any of them based off of pure numbers (i.e. table and depth). One has good angles, but other than that, I'd pass...on all.
Of the 5 you posted, only the last one has an Ex cut grade, but I think you would need pictures (scope, etc) of anyone you would consider. I would not buy any of them without seeing them or at least have a good return policy.
When you see the diamonds in person you are simply looking to see which ones you like the most. Unless you are buying the stone strictly with the purpose of selling it nothing else really matters. Try to get them to let you see the diamond in different lighting, most jewelers have the lighting set up to show off the diamonds. Try to see it in direct light, with almost no light, near a window and even outside if possible. If you want purchase an ideal scope to take with you and you'll be able to more accurately tell how much light it is reflecting.
All of the tools, and angles and specs that anyone on here swears by are just guidelines. Some people know exactly what specs the diamonds they like the most will fall into. Most just rely on generally accepted ranges that have been proven over time to provide the highest percentage of stones that most people find most beautiful. You may want to use these tools to help you request what you want them to pull out for you but once the diamonds are in front of you it is all about what you like the most. If you look at stones side by side and find you like one more than the other and you feel it is fairly priced then thats the one.
In fact if you are going to look at stones and both you and the jeweler (or broker) have time then I would even recommend looking at stones that are less than Ideal, There is a very good chance that you will choose an Excellent cut diamond with good color and clarity but there is no way you can know what you like until you see it.
