Can I wire 2 ceiling fans and 5 ceiling spot lights and 3 closet ligthts on a singe circuit with 12 ga wire and a 15 amp breaker?
Or should I wire the 2 ceiling fans on a separate circuit?

There should be no problem putting it all on a single 15 ampere circuit. Likely in the worst case scenario, each fixture would consume ~100 watts. That would be using large 52" fans, and 100 watt bulbs in each fixture. With the 10 fixtures, that would be 1000 watts (10 * 100 = 1000). A 15 ampere 120 volt circuit can provide 1800 watts of power (15A * 120V).
More realistically, you're going to be using lower wattage fixtures, especially nowadays with CFL and LED bulbs becoming more common. Here's some calculations based on various wattage devices.
Since it's a 15 ampere circuit, you'll only need 14 AWG conductors. Unless there's a specific reason you're using 12 AWG instead, which is also fine.
