I just wanted to know if there is any reason to not do these combinations on some new lines im adding.

I am using all 12/2 wire and probably 15amp fuse, maybe 20 amp

#1 - 1000W OTR microwave
#2 - 25 cu ft side-by-side fridge, Dishwasher,
#3 - 5-6 20W dimmed halogen under cabinet puck lights, TV Electronics (PC Computer, 65" TV, Router, PS3, and a couple very low consumption electronics)

Is there any reason why I should adds the halogen lights to maybe #1 or #2?

Depends where you are. Different jurisdictions have different rules. There is no reason to run 12 gauge on a 15 amp circuit and if the existing circuit is 14/2. Adding 12/2 would be confusing to someone in the future and might replace the 15 amp breaker with a 20 assuming the entire circuit was 12/2 . 12/2 is harder to work with.

Personally , I like my fridge on its own circuit. I don't want overloaded circuit blowing a breaker and shutting off my fridge. A 1000 watt microwave is close 2/3 of the capacity of a 15 Amp circuit. So you might want to keep that one seperate. Kitchen receptacle circuits can only have other kitchen receptacles on the same circuit.

An OTR MW requires a dedicated circuit.

The
Kitchen and fixed in place appliances have special rules under the code. Lighting cannot be on the small appliance circuits.
