Chopin Rolled Chords

[pianos1]

In measure 8 of Chopin Etude Op. 10 No. 5, there is a rolled chord in the left hand and a single note in the right hand.  What is the order of the notes combined? 

Last (top) left-hand chord note together with right?
First (bottom) left-hand chord note together with right?

In measure 22 of Prelude Op. 28 No. 2, there is a right-hand chord roll and an octave in the left hand. How is this played? 

Last (top) right-hand chord note together with left-hand octave?
First (bottom) right-hand chord note together with left-hand octave?

In measure 8 of Prelude Op. 28 No. 3, there is a right hand chord roll, and a single left-hand note.
Same questions.

In measure 71, Prelude in C# minor, Opus 45 there is a right-hand chord roll with a grace note before it, representing the lowest chord note.  There is a tied note in the left-hand. How is this played?

Thanks.
