Can we mix lights and receptacles in one circuit

I have a 20 amp/12 size wire circuit where it loads one receptacle and four lights. call it "circuit 1". Is this ok? I heard light should be on a 15amp circuit.

I want to add another light to "circuit 1" using a 14 size wire. Is this right? Can this cause a fire? Can I mix wires sizes at all?

As long as it is not in the kitchen, some baths or the laundry.

That is common, but not required.

No, you should not use #14 on a 20A circuit. A 20A circuit requires #12 wire.

Tnkx ibpooks. You guy are quick!

Mixing wires: If the circuit is 15 amps/14 wire size. Can I add a 12 wire just to add another light?

Thanks again ibpooks

Yes you can. You may always upsize your wire... but it's sometimes considered bad practice since someone down the road might notice a 12ga wire and assume it's for a 20A circuit. But code-wise and safety wise, no problem.
