There must be 2 (two) circuits for receptacles in kitchens.
This means, 4 receptacles in one circuit, 3 receptacles in another circuit or, two circuits running on the 7 receptacles.
GFI receptacles are required when close to the sink, and I don't think your kitchen sink is that long to connect 7 GFI receptacles close to it.
You can install the GFI receptacles over the counter close to the sink, the rest can be regular receptacles. You are not adding more safety or anything similar by using GFIreceptacles when not required by code.
But, it's your money.
Enjoy your kitchen.
