Alpha Mensae is a yellow-orange main sequence dwarf star of spectral and luminosity type G5-6 V, with about 87 percent of Sol's mass, 84 to 91
percent of its diameter (Perrin and Karoji, 1987, page 236; and Johnson and Wright, 1983, page 659), and around 80 percent of its luminosity. The star
may be as as enriched (102 percent) as Sol with elements heavier than hydrogen ("metallicity"), based on its abundance of iron (Cayrel de Strobel et
al, 1991, page 285).

And guess, another sun like star! But let's go on...
Rem.: this star is not often found as referred by its Gliese number, rather by its HD13435 designation
Very little can be found about that star, but its stellar class K1III makes it a giant or subgiant orange or redish orange star.
Rem.: this star is not often found as referred by its Gliese number, rather by its HD9540 designation
Again, a not popular star, with a spectral class of K0V. This makes it a main sequence dwarf, more red/orange than the sun (thus cooler).
I will leave the last 2 stars on the map except for the sun (Sol), Zeta 1 and Zeta 2 Reticuli, apart for the moment. I'll come back to them later.
So let's summarize a bit here...:
Star name -- Distance (ly) -- Spectral Type -- Visual Magnitude
Gliese 67 -- 41.4 -- G2V -- 4.96
107 Piscium -- 24.4 -- K1V -- 5.24
Tau 1 Eridani -- 45.6 -- F5/6V -- 4.47
Tau Ceti -- 11.9 -- G8Vp -- 3.49
82 Eridani -- 19.8 -- G5-8V -- 4.27
54 Piscium -- 36.2 -- K0+V -- 5.88
Kappa Fornacis -- 71 -- G2V -- 5.80
Gliese 95 -- 41.3 -- G5V -- 5.82
Gliese 86 -- 35.6 -- K0-1V -- 6.12
Alpha Mensae -- 33.1 -- G5-6V -- 5.08
Gliese 86.1 -- 183.6 -- K1III -- 7.06
Gliese 59 -- 63.6 -- K0V -- 6.98
We see that all the stars labeled on the map are of a stellar type comparable to the sun. We also see that with the exception of Gliese 86.1 and
Gliese 59, they all are within 50ly, which makes them in fact close neighbours.
If so far, for none of those stars, a planetary companion supposed to be able to harbour life as we know it, has not been detected, we must notice
that most are acceptable candidate. The reference links tells more: some of those stars are prime candidate for the search of such planets!
What about Zeta 1 and 2 Reticuli then...?
First thing that we must notice is that they are respectively G2V and G1V. That's very similar to the sun. Also, they are situated at 39.5 light
years from us, a distance remarkably in line with all the other stars quoted above.
ζ1 Reticuli is slightly less massive and luminous than the Sun. Spectral class of the star is G2.5 V.
ζ2 Reticuli has a very similar mass and luminosity to our Sun. The spectral type of the star is G1 V.
Sol Station tells us more about this double star system: (Reference
(...)Zeta1 Reticuli has become one of the top 100 target stars for NASA's planned Terrestrial Planet Finder (TPF)(...)
Once thought to be old Population II, galactic-halo-type subdwarf stars, Zeta1 and its companion are more likely to be old disk stars (Da Silva
and Foy, 1987), that may be as much as eight billion years old.
