Should there be an o ring between the the O2 housing and parts that gose on to the wastegate pictures below I have the o ring seal on the wastegate but not on the 02 housing?

You need a fire ring between the wastegate inlet port and the O2 housing. You don't need it in wastegate outlet port side (dump side).

I have an extender so the wastegate dose not mount on too the 02 housing directly. I have the fire ring from wastegate to extender but no o ring to the extender to 02 housing I need one there also?

As long as the flanges are not warped and sealing good, usually you don't need any gasket for v-band. The fire ring is to seal the wastgate, the wastegate won't work as it should without it.
