These are southern suspected or recently named variables very
bright and suitable for observation.
V996 Cen has been classified as an Lb star with a 0.35 V
magnitude range (Hipparcos observations. GCVS lists 9.6 - 10.5 p) It's a cool C
star (B-V = 3) and its amplitude seems to be greater since my observing records
only show it rising:

NSV 6507 (HD 121658) is located near V996 cen and shares
the same features with it: a C star, very red (B-V = 2.9) and classified as an
Lb. The GCVS range is photographic: 9.8 - 10.5 p. It is also very similar in
brightness since both are 7th magnitude stars.

V528 Car is a red supergiant (M2Ib, B-V= 2.0) that shows a
0.21 mag. amplitude according to the Hipparcos Catalogue. The range is too small
for visual observation but I'm monitoring it in order to find a possible greater
range than the one given, as in the case of the forementioned variables. However
it seems it's not the case.

Another small amplitude (0.20 according to HIP) variable is
the red giant ( M3-M4III, B-V = 1.7 ) classified as V1086
Sco.

NSV06021 in Musca ( HD 112094 ) is the last one I
have. Another red supergiant ( M2Iab, B-V = 2.0 ) GCVS gives the range
9.4 - 10.0 p and the possible type as SRc. I've been observing it two years and
very little has happened which probably agrees with that
classification.
