Hello all, I just got my new Giant Contend 3 road bike and it seems that my front derailleur is making quite a bit of sound and I AM 100% SURE ITS THE chain.

I am going to refer the chains as 1,1 or 1,5 --- the first number is the front casset and the second number is the rear casset. I have a 8 speed Shimano Claris set.

So whenever I'm on my bike, the front derailleur makes a little sound when I'm on gears 1,1 and 1,2 but the sound goes away at gears 1,3 1,4 and 1,5 , then the sound gets pretty loud at 1,6 (this is usually when i switch to the big ring on the front derailleur), 2,4 2,5 2,6 2,7 and 2,8.

I feel like the sound is there because of the derurallier's angle to the rings, but I'm pretty sure its not because the rings are aligned like how it is on the ParkTools Front Derraler video says. Or bikes are just more sensitive then I think.
Well hopefully something works.....

Usually new bicycles come with a warranty and this sort of thing is covered under that. I'd recommend taking it back to the bike shop and they'll be able to fix it in a matter of minutes. At least that's been my experience with Giant bicycles in the past because parts take time to bed in / cables stretch and thus gears need adjusting in the first few months.

Unless the chain is actually making contact with the front derailleur cage, the front derailleur is not the cause of the noise in some gears

You can look and see the chain rubbing if it is indeed rubbing ( put a piece of paper between your chain and the derailleur cage, and move your crank arm backwards, if it's rubbing it'll be obvious).
If it is, take it back to the shop you bought it from, and tell them to make your new bike right. If that's not an option, there's lots of Youtube vids on derailleur adjusting.

FD adjustment is a bit tricky, but thankfully once done it usually holds stable for a long time. I say tricky because cable tension has to be just right, and some in- line adjusters aren't all that great. I'd advise to take tension out of limit screws before turning them, by moving derailleur by hand, so you don't strip the head on the screws over time.

if you've watched the park tool video (I adjusted my FD yesterday and watched the video later that day, bass- akwards you might say) you know all the things to set. If you don't have a bike work-stand you should probably take it to your LBS for adjustment. I rode quite a lot of years before buying a work-stand. It's the first thing I'd buy after the bike if i had it to do over again.

Before you screw it up worse, ask the guy who sold you the bike to fix it. Service is why you didn't buy a WalMart bike.

So, it is the chain that's rubbing the front deurallier and I believe the chain rubbing issue has been solved. I aligned the cage to the casset and tweaked the high and low deraller and now the chain isn't making any more noise. Thank you guys for helping!

Feels good to fix something yourself. Good job!
