Overall, these are good shots. Specially when you consider the high contrast lighting under which they were taken.
Image processing tends to be personal preference and is often a constantly growing and changing evolution. However, there are many constants that apply across the board, regardless of the final product; exposure being highest on the list. For weddings you need to understand what the end use of the images are going to be. If it is a catchy advertisement then this high contrast, artsy look can work. Just remember women would prefer looking softer on camera. Likewise with the detail in their dress. No one wants to spend thousands of dollars on a wedding dress only to have all their images come up bright white with no detail.
Of all the images number five (the kiss) is probably your best. It has a warm, inviting, almost magical feel to it. It maintains that film look you desire without losing image quality to high contrast.
While the photojournalistic approach to wedding documentation is very popular, there is a thin line between looking like a newspaper photo and a 'capture-the-moment' image that makes you feel like you are right there. Just keep this in mind, if it helps... if it look like it belongs in a newspaper then it likely won't look good in a wedding album.
The nice thing about digital images is that they can be processed in any number of ways without long hours in a darkroom. Give yourself permission to experiment. Don't feel like you need to 'produce' all the time. Experimentation often leads to some interesting discoveries.
Best of luck
