Case: SRM-01
Motherboard: A320M
Processor: Ryzen 3 1200
Power supply: 500 watt
Hard drive: 1 tb
Ram: One 8gb DDR4 2400 MHz CT8G4DFD824A (Should I buy the same stick to have 16gbs?)
Graphics card: 2gb R7 350 (I was thinking about upgrading this to a 1050 but I don't know if it will fit)

Performance wise, it is better to run with two ram sticks to benefit from dual channel. You must buy the exact same ram to make sure it will run in dual channel otherwise you will either run in single channel or even worse have post/bsod problems. Ryzen loves fast memory, buy the extra ram and crank them up as far as it goes, maybe you can hit 2933 mhz

If you can source the exact same stick, then go for it! If you can't, I'd suggest going for a 2x8GB DDR4 ram kit. On the matter of ram, you've got a RyZen platform, for which it's ideal you source a dual channel 3200MHz ram kit. i.e, 2x8GB DDR4-3200 ram kit. RyZen's Infinity fabric like high frequency ram.

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, particularly AMD can be very sensitive to this.
This is more difficult when more sticks are involved.
That is why ram vendors will NOT support ram that is not bought in one kit.
It is safer to get what you need in one kit.
But, it is a bit more expensive because of the added matching of all the sticks to insure compatibility.

ryzen is particularly picky about ram.

Adding ram is not 100% guaranteed to work.

What is your plan "B" if the added stick does not work?

My suggestion:

First, verify that your current ram is supported.
Go to crucial, the maker of your ram and access their ram selection app.
Verify that your ram is explicitly supported by your motherboard.

Then, look to see if there is a 2 x 8gb kit that is supported and matches your original stick.
If so, order that, and you will be guaranteed 16gb.

If your motherboard supports 4 sticks, then try and see if your 8gb stick plays nice. If it does, good, you now have 24gb.
If not keep the 8gb as a spare or sell it.

Your motherboard supports the following ram on the QVL list:
http://www.asrock.com/MB/AMD/A320M/index.asp#MemoryRR
Pick a kit from the list if you can.
Ram faster than 2666 will need to be overclocked, likely with xmp profile.
Buy the speed you can afford,
Integrated graphics responds well to faster ram.

If you have aspirations of upgrading with a discrete graphics card in the future, ram speed is not so important.

You will be ok with any ram on the QVL list.

Technically, ram faster than 2666 is overclocking,meaning that the voltage will be greater than 1.2v. But the ram is designed to handle that.
Higher speed ram will have several XMP settings imbedded in the ram itself.
When you select a particular xmp profile in the bios, the motherboard will use that info to set the proper voltage and timings .
If the price difference is not too great, I think you should look for a faster supported kit.
All ram will work at default settings if you should have any problems.
