PLEASE PLEASE PLEASE DON'T !!!!!!
I take it you haven't read the raid wiki?

The bad news is your array is well borked. The good news is I don't
think you have - YET - managed to bork it irretrievably. A create will
almost certainly trash it beyond recovery!!!
I think we can stop/revert the grow, and get the array back to a usable
state, where we can force an assemble. If a bit of data gets lost, sorry.
Do you have spare SATA ports? So you have the bad drives you replaced
(can you ddrescue them on to new drives?). What was the original
configuration of the raid - you say you lost three drives, but how many
did you have to start with?
I'll let the experts talk you through the actual recovery, but the steps
need to be to revert the grow, ddrescue the best of your failed drives,
force an assembly, and then replace the other two failed drives. No
guarantees as to how much data will be left at the end, although
hopefully we'll save most of it.
Cheers,
Wol
