What age recommended?

Depends on the Lego skill level of the child. If they have experience with Legos and following the directions, 6. If they need assistance with Legos I would wait till they're 7. Can probably entertain them through 8.

Where can you get replacement rubber bands? Or can you just use similar sized ones?

I get them a bunch at a time from office depot, not sure of the size I match them as close as possible.

Does the klutz lego crazy action contraptions craft kit really contain: 6 separate items including parts and instructions ?

It contains an assortment of parts that will make 6 working contraptions. You can't make all 6 at the same time as some pieces are used in several items. The book is the instruction manual. My 6 year old got the hang of it and made all 6.

Why is advertised that it's a set of 16 projects (covers, pages #4, 6, 46) when there are only 11? (14 max, when counting the primitive Bored Games)

Maybe for the child and you to create additional projects. Making tour our creatativity.
