When and where to look for Puppis

Puppis crosses the meridian — its highest point in the sky — at local midnight around January, which makes the months from December to February the easiest time to find it in the evening. It spans declinations -47.3° to -22.9°, so visible from everywhere south of about 43°N.

The quickest way to find it is to open the live AR sky map and point your phone at the sky — if Puppis is above your horizon right now, its figure is drawn in the position it genuinely occupies above you.

Spectral class is a temperature ordering, running from O at around 30,000 K down to M below 3,500 K. A constellation is a direction, not a group, so this is simply what happens to lie along that line of sight.

The closest catalogued star in this direction is HD 69830 at 40.7 light years. The most distant is HD 68450 at roughly 3,198 light years — stars that appear side by side here are nothing of the sort.
