In all of these there are fundamental design basics issues….
Typography is way off in all of them
Spacing and margins are inconsistent and inaccurate
There is nothing unique to any of them
Icons/images looks stretched and mis aligned in places
They all feel slightly incomplete
The design style is very outdated and colors do not really work.
You need to pick one and start a fresh using that building block and focus on attention to little details, consistency and compare it to existing files for the quality of design
It can be done I believe with jquery but either way it will require some clever custom coding.
I’ve never tried it but this might work also http://tabbervilla.com/wordpress-post-tabs-pro/features/
You need to work on the slides because the demo is what sells you file and if it looks bad or lazy then the reviewer will not approve it in the first place.
Why are you not including the slides? Most files on here do.
To me (and of course just my Opinion) the main nav typography is far ok big, it needs further spacing and feels clunky.
As for fundamentals – again just my view but it feels outdated and like a free theme and there are issues with design basics in the layouts, spacing and especially type.
Again all this is all only my opinion but after years of being on here as working with files from here one thing I can guarantee is that approval relies on not being lazy and cutting corners and most of all attention to detail
