I have a 7.2v 1200 mAH battery charger which I use for my RC car. I intend to use the same charger for my RC plane's rechargeable battery pack with a rating of 7.2v 600mAH. Will this work?

Are you sure your charger output is rated in volts and maHours? I thought I had seen them rated only in voltage and current. I checked 2 of the small ones I had close by and their outputs are just rated in volts and ma.
The batteries themselves could be rated in maHours. That would be how long they can put out how much current before they're fully discharged. If my suspicion is right, and you used a charger that would try to pump too high a current in (that would mean it's trying to charge it faster than recommended), the battery might overheat.
If you double-check and find your big charger is 7.2v 1200 mA, then if you have 2 battery packs you could charge 2 at once (in parallel). Assumining they're equally discharged, the output current would divide about equally in 1/2 between the 2 packs.

Yes. The voltage is the key; if that matches, you're good.
