You can own up to 2 of these, but can summon all four to your datapad if they are in pet/deed forms.
All non-quest Pre-NGE Creature pets were made by Creature Handlers & Bio-Engineers, and since these prof's no longer exists, no new creature pets can be made.
But anyone who got one, or have one before the NGE still have them, those pets above lvl 10, can not be summoned, or used. With the exception of mounts.
Faction Pets have been removed from Faction Recruiters, so only veteran players who got one, still have them.
You can own up to 3 of these.
Their is a comm that you can now get at Rebel Lieutenant or Imeprial Lieutenant, that allows you to summon three troopers to defend you.
Droids, are made by Trader/Engineering (Droid Engineers)
You can own up to 5 of these.
Currently the best pet, a new player can get, at least the highest lvl, is the droid, they can be lvl 60.
Creature Pets are only lvl 10, but can also be mounts, and faction pets are no longer an option.
