same predictions for different satellites

In the quicksat output of friday evening july 16, some predictions are
exactly alike: 23.38.16 (local time,= 2H ahead of UT), 218 (Azi), 47
(Al), all first line. The satellites are:
23579 Spektr, 23848 Priroda, 25632  99007 A, 25664  99015 A. The two
Kvant satellites, coming about 1.40 minutes later, also have common
predictions.

I am not an experienced satellite observer (just started), so I don't
know what this means. Are these all parts of the same sattelite (MIR)? I
didn't see any one of them. Are they not bright enough? I thought I saw
spektr, but it became so bright, I think it must have been MIR itself.
The prediction for MIR was a couple of minutes later, but the azimuth
almost the same. When I was looking for Spektr and the other satellites
I didn't look at my watch and a couple of minutes pass quickly.

My coordinates: 52.298North, 5.25East, Alt 2m

Can someone shine some light on this? If possible can someone give me a
list (or point to a website with this information) of all parts of the
same sattellite if such is the case?

Thanks in advance,

Jan.
