I want to buy a new PC, I would install more than 8 Gb RAM.

-easy videoediting, watching many youtube videos at the same time in 1080p , watching live streams,
having 10 tabs in browser open at the same time including the youtube videos,
working in fl studio when browser is open, watching websites that have big filesize pictures in it ,
websites and programs should open fast, google earth, audacity recordings, photoshop

I would not buy the setup you listed, it is all but obsolete.

For what you want to do, buy a 2 x 8gb ram kit; it should be sufficient.
The key to performance is a ssd. 120gb is simply too small for windows these days.
Look for 250gb at least, more if your storage needs warrant.

I think integrated graphics would be ok for HD movie playback.
You can always add a discrete graphics card later.
A 6 thread i5-9400 will have a decent HD630 graphics adapter.
The i5-9400f is cheaper, but you would need a discrete graphics card.
 
AMD A10-8750 CPU supports at maximum 2133 MHz data rate.

Your board support 3200MHz RAM but your CPU isn't.
And if I have 2x 8GB RAM, does it make a difference if one has 2666 MHz and the other one 2400Mhz?

All your RAM will be running at 2400MHz if you do and mixing RAM is not recommended.

What you need is a 2x8GB RAM KIT that were tested to work without any instability together.
 
And if I have 2x 8GB RAM, does it make a difference if one has 2666 MHz and the other one 2400Mhz?
If your ram is running ok, then perhaps not.
Both will run at the lower speed.
But... and that is a big but.
Ram must be matched to run properly at advertised performance.
Disparate sticks not from the same kit are not matched.
That must be done in the factory.
The same product code, even from the same ram wafer are not necessarily matched.
You are exposed to inconsistent errors.
Perhaps you are ok, perhaps not.

What is your plan B if two sticks are incompatible??
Best to buy a single 2 x 8gb matched kit.
 
If I have only 1 x8gb DDR4 2666 MHz, and I want another 8 gb, do I have to buy any Ram thats DDR4 with 2666, but it does not matter from what manufacturer?
No, you caan not buy just any ram and expect that it will work.
If you want 16gb, buy a 2 x 8gb kit of whatever speed your motherboard supports.
Sell the old 8gb stick, or keep it as a backup.

Ram is sold in kits for a reason.
A motherboard must manage all the ram using the same specs of voltage, cas and speed.
The internal workings are designed for the capacity of the kit.
Ram from the same vendor and part number can be made up of differing manufacturing components over time.
Some motherboards, can be very sensitive to this.

If you just buy a second stick, it may work, Your odds are good.
But, if it does not work what is your plan B??
