Many guys prefer easy girls who put out, and there might be a strong correlation there with women who go through much length to appeal to men even if they have to subdue any part of them that is natural or real. However, it's probably good to note that tons of guys date tall women, or short, or brunettes or blondes, or etc etc. Tons of guys date guys.
So what I mean to say is that it doesn't matter what guys prefer in general because you will never be dating every man in the world. Just be yourself and find someone who likes you. Simple enough I think.
It seems that I type this answer more and more. Everybody has different tastes. Does every guy catch your eye? Probably not. There are certain things that you find attractive. To the pictures you shared, yes, the two hot blondes are eye catching and built. No denying it. However, girls like that for a long term relationship - that's where I begin to question if they would be correct for that. I personally find the other two more attractive with a natural look.
As you may find with guys, "hot guys" may have a tendency to not treat you as nice. They have their looks and biceps to rely on. A guy who may not be as good looking (nerdy even) is more likely to be a nicer guy. Girls can be very similar. The first two pictures may not be the nicest girls since they are 'hot'.
