The rocket and satellites for this mission were all developed by the Eighth Academy of China Aerospace Science and Technology Corporation.

Seems to be incorrect as http://www.spacechina.com/n25/n2014789/n2014804/c3405007/content.html says:

执行本次任务的火箭由中国航天科技集团有限公司八院研制，本次成功发射的实践六号05组A星、B星分别由八院、五院抓总研制。
The rocket for this mission was developed by the Eighth Academy of China Aerospace Science and Technology Corporation. The successfully launched A and B stars of Practice 6 Group 05 were developed by the Eighth Academy and the Fifth Academy respectively.

2021-122A/49961 in 454 x 469 km x 97.36° (SJ-6 5A)
2021-122B/49962 in 457 x 470 km x 97.36° (SJ-6 5B)
2021-122C/49963 in 457 x 471 km x 97.36° (tbd)
2021-122D/49964 in 289 x 464 km x 97.27° (CZ-4B upper stage)
2021-122E/49965 in 421 x 439 km x 97.44° (tbd)

Those two TBD might be Huawei’s Sats？

E is a fast decaying object. Very fast for its initial orbit.
C is probably an adapter separating A and B during rocket flight.
There is no Huawei stars in this launch. One was launched Dec 7, named Baoyun; the six you've mentioned were not planned to launch before 2022.

[Alter Sachse]

The orbit is lower than for the previous SJ 6 satellites.
The launch was referred to as "Group 5". There can be more than 2 satellites.

Mission code "01-141".

[Liss]

08:11:30 was probably the planned launch time.

[input~2]

Mission code "01-141".

With my own listing of mission codes, I  find "01-141" for this launch if I count the Chinese Space Plane test of July 16, 2021 from Jiuquan as orbital with mission code "01-133"

Well, the two are now 1.7° from each other after the series of maneuvers of both spacecraft.
