I want to c0t4d0 with c0t6d0, c0t4d0 has some HW erros.
How can I do ?

Did you mean you want to replace with target 7? It looks like target 6 is already a member of the array. I think you want to use metareplace d5 c0t4d0s0 c0t7d0s0.. Check out the man page for metareplace for more.

Target 6 is not part of array, is it fine if I do metareplace, coz RAID is with 3 disks only

It sure looks like your array consists of targets 6, 3, and 4.
