Attached is the photo of my pool, now in last mirror one drive failed, currently its running with 1 drive, what happens if i select the mirror and click remove option given, will both drives be removed and pool run as usual? i have enough free space to run from other 4 drives.

I don't think you can do top-level VDEV removal on a pool that's not healthy.

You would first need to detach the failed disk, making the remaining disk from the mirror a single-disk/stripe VDEV.

You could then remove that top-level VDEV (assuming you're on a sufficiently new version and the pool version is right... and you have sufficient space on your remaining VDEVs to take the data).
