How many beers will the 20L hold in it? Also is the strap strong enough to hold this full of beers?

The 20L is about 15 inches. If you did a nice circular stack with the cans you might be able to fit a little more than a 12 pack. Or do a circular stack and fill the middle with ice to keep them cold.😉

What are the dimensions on the 40L?

40L size is Height 16.9 x Bottom Diameter 11.9 inches after top is rolled 4 times.

How many pounds of kibble fits into 20L in these travel dog food bags?

Depending on the dog food brand, a bit less than a 10 pound bag.

Family of 5 going on cruise, spending day on beach. What size would be best to carry everyones things? Do i need to 2?

The biggest is the 40L, I carried a cozy thick coleman sleeping bag (that is all). I think my answer will be: "It depends" in how you define things for 5 people. I hope the fact that that same size bag carried a sleeping bag will help you with an idea of how thick it is. Do a Youtube search by writing "Marchway dry bag" and lots of info may pull to help you deeper. Have a good time.
