No worries. 5 Combaticons is 5 Combaticons, regardless of how they're packaged.
The answer to both your questions lies in Article 08:
Decoys, Statues, busts, PVCs, meal/candy toys, kits etc. do not count. e.g.:
- Super Collection Figures don't count
- Mega Collection Figures don't count
- Mighty Muggs don't count
- Be@rbricks don't count
- Model kit style Arms Microns don't count
So all meal toys (Maccas, Red Rooster etc.) do not count. If Maccas toys interest you, check out the Armada Happy Meal toys... they're the best made meal toys IMHO (especially Hot Shot and Starscream).
The model-kit style Arms Microns don't count because they are model kits, not pre-made action figures like orthodox Mini-Cons. Yes, they transform, but so do some of the other confectionery model kits, like Death Zaras or even Tripledacus who can transform and combine. But those model kits have never counted before, so for the sake of consistency it's been ruled that the model-kit style Arms Microns do not count under the UCM.
