Did you flash the fuses first before use ?
Also known as burning the bootloader on ATTINY.

Doesn't usually burn a proper bootloader but simple does a FUSE setting ready for future use.

Something is different between these 6 specimens. Either you uploaded different code or forgot burn bootloader to set fuses on the non-working ones, or there are bad connections in the hardware of the non-working ones.
