Why are all Singapore Airlines 777-200ER but some with derated engines?

SQ have never had any 777-200s that were not built as 777-200ERs. All SQ 777-200s are consider by Boeing to be 777-200ERs.

I still don't know what you mean. All 777s have been built by Boeing.

And I meant original B772s when I mentioned Boeing built B772s. Not B772ERs masquerading as B772s in SQ fleet.
Can they use the extra fuel tanks on those with derated engines?

Thanks very much
Even if the engines being used is different (772 = RR Trent 884, 772ER = RR Trent 892, 77W = GE90-115B), the difference it makes for the pilots is minor. They would only have to worry about what primary engine parameter they have to monitor on the EICAS (EPR for RR powered 777s and N1 for GE powered 777s)
Going a bit off topic too here, but this is why Airbus utilizes "common cockpit philosophy". This means that the the cockpit layout is almost identical from the A318 to the A319, A320, A330, A340 and begins to slightly differ on the A380. I know of Airbus pilots who have told me that due to the similarity in the cockpit layout, an Airbus A320 pilot would only have to go through a "cross-crew qualification" course that lasts for several days and voila!, he/she is eligible to fly the A330. Same goes for A330 to A340, etc. This is why most low-cost carriers utilize an Airbus fleet, AirAsia, for example. A320 pilots can easily fly the A340 in AirAsia X in a matter of days, and the training doesn't cost much. Airbus aircraft are also generally cheaper than the Boeing rivals due to cost-efficiency.Such a gentle way about you / All around the world / Wouldn't go away without you / Singapore Girl, you're a great way to fly

they will have the same range and MTOW of the 772ERs but still the old oxygen system of the "772"
they are unable to do the european runs due to oxygen requirements over high terrain over kabul

forget to add..they do not have crew rest facilities so you won't see them being used for JNB too
