Would it work with marbles if the little coaster car gets lost?

Sort of works for some track configurations. Marbles are faster than the car and jump the track easily.

is it too difficult for a 6 year old?

My son received it at about 6 1/2. He liked building with it for fun, but without the guiding cards. As he got more familiar with the pieces, he started trying the easier builds and really enjoyed it. I would say if your 6 year old is a builder and already completing Lego sets for older kids (8+), they would enjoy growing with this game. Hope that helps.

Can 2 sets connect together?

that is a great question! there is no scaffolding to connect the black bottoms but there is nothing preventing you from putting them side by side and attaching the pieces from one set into the next

For older kids, such as 5th graders, do you recommend combining 2 kits for them to have more pieces to work with or is 1 kit enough (won't be bored)?

Not really. This is a game, not a building set. You get cards that show you the puzzle and you have to "solve it" by building something that meets the build requirements (i.e. what shows on the card). So having more pieces won't do anything extra for those puzzles. Now, if you want to approach this as a builder set and just let the kids build what ever they want, then more pieces could be good. But I wouldn't recommend it.
