No. When A sends 0.52 to B, B gets all of the 0.52 in his A <-> B channel. Then B sends 0.51 to C and C gets all 0.51 in his B <-> C channel. Then C sends 0.5 to D and D gets 0.5 in his C <-> D channel. So if the A <-> B channel closes, D has his 0.5 from the C <-> D channel and A still has spent 0.52 which is now with B. With LN, A doesn't actually directly make an output to D unless they have a channel open with each other.

And finally C just a single output of 0.5 to D? Also, if the A->B channel ends, and the 0.52 tx is commited to the blockchain, D has his money and so does B (the 0.2 fee), but what about C and D? | |

The fees work via the differences in channel balances. For example (values not representative of actual), for a route of A -> B -> C-> D-> where A sends D 0.5 BTC, A, via its channel with B, would send to B 0.52. Then B, via its channel with C, would send to C 0.51. Then C, via its channel with D, would send to D 0.5. In this way, B and C collect their fees from their channel balances and D receives the amount that he asked for.
