All,
Using detailed doppler measurements I find that QB50p1 is object 40025, 2014-033R, and QB50p2 is object 40032, 2014-033Y.

Using detailed doppler measurements I find that NanosatC-BR1 is object 40024, 2014-033Q.

Using detailed doppler measurements I find that POPSAT-HIP is object 40028, 2014-033U.

Using detailed doppler measurements I find that ANTELSat is now object 40034, 2014-033AA. Yesterday the JSpOC decided to exchange the TLE set of object 40034 with the set of object 40049, 2014-033AR. So up to yesterday ANTELSat was object 40049 but as of today it is object 40034.
Doppler measurements show that DUCHIFAT is almost certainly object 40021, 2014-033M. But at this time the distance between objects 40021, 40022 and 40023 is too small to be absolutely sure. Especially the temperature induced frequency drift on the downlink signals makes it hard to do a good assessment of the measurements.

All,
Using detailed doppler measurements I find that DUCHIFAT is definitely object 40021, 2014-033M.
Operators of DTUSat 2 confirm that their satellite is object 40030, 2014-033W.
So now it is up to Planet Labs to determine which of the objects 40022 and 40023 is FLOCK 1C-10 and which is PACE. The separation between these satellites is still less than 2 s, i.e. less than 15 km.
From doppler measurements I can confirm that VELOX 1 is object 40057, 2014-034E.

All,
Doppler measurements suggest that UKube 1 is either object 40074, 2014-037F, or object 40075, 2014-037G. The separation between these objects is now only 1 s, so no more than 7.5 km.
It is not easy to carry out meaningful doppler measurements because of the limited transmissions from the beacon in varying modes and both long-term and short-term frequency drift and other instabilities on the beacon transmitter.

Using doppler measurements I find that Dauria DX 1 is object 40071, 2014-037C.

All,
Finally the separation between UKube 1 and AISSat 2 has increased to about 60 km. And with the telemetry beacon transmitting a continuous signal, it now became possible to identify UKube 1 using doppler measurements. It appears that UKube 1 is object 40074, 2014-037F. So the JSpOC's initial guess appears to be correct.
