One general is a priority - they provide morale bonuses compared to captain-led armies and the generals get better if they lead an army. But you only need one for this - their stars only matter if they lead an army. Having multiple generals in a stack is fine - as Omanes said they are elite heavy cavalry. Aside from having great stats, they also have two hit points (twice as hard to kill) and regenerate some losses between battles. What I do is have one general per half stack and two per full stack (the second being a reserve leader).

Beyond that your priorities may depend on the faction you are playing. Rome excels in heavy infantry so that would be first for me. Parthia excels in horse archers, so could even do without any infantry.

If we are talking Romans, I think a core of 4+ heavy infantry is a good basis. They can handle most unit types. Historically, the core of a Roman army would be heavy infantry plus some lighter allies or auxiliaries.

In game terms, against the AI, I often like 3+ archers as they can kill without loss. They are essential against horse archers.

More cavalry is great for any faction, but historically it is rather unRoman, so I try to ration myself to a couple at most.

Romans don't really need spears. In the game, the Roman heavy infantry can handle cavalry about as well as spears available to Rome.

Pre-Marian Roman armies used a fair amount of light infantry, but in game terms they are not necessary.

If we are talking generically - not just Romans - I would favour a balanced force. So don't prioritise one unit type, but get a little of each. Most unit types have a role and try to coordinate among the combined arms makes the battle more fun than relying on a one trick pony.
