[ Maintenance & Repairs ] Open Question : dual circuits int the kitchen?

Ive up dated the kitchen outlets with GFCIs' I have 4 outlets that are on their own dedicated 20amp outlet. next to one of theise outlets is one that is tied into the garge and entry way lights. This same outlet is close enough were i can run wire to a outlet next to it (one of the 4 on the dedicated outlet) can i do this? i think I need 2 dedicated circuits? I also have a outlet that is tied into the same circuit as the fridge, but is GFCI. is this ok? with this outlet count as my second outlet?
