Yes, it will just run at the speed of the slowest ram

But keep in mind. Some boards are picky about ram

how lower will it run, i want good speed

what do i need to get atleast 2133mhz?

Better yet, sell the RAM you already have and buy a 2x8GB 3000MHz kit thats on the motherboard QVL.

Slowest meaning slowest of the ones you have installed and that is 2133MHz so both your existing and new memory will operate at 2133MHz.
Even though its not guarantied.
Optimal RAM configuration is two of the same. Using more than two dimms it taxing the memory controller more even they are of the same kind.
Mix matching memory it should works its just you have to test it out to be sure.

so if i buy other company ram at 2133 same as current ones speed, would i still need to worry?

You don't need to worry the 2400 will run at 2133. If you get BSOD then it may be an issue

It will be still mismatching rams.
Ram has Frequency timings and voltage.
You can't set different values for the different types of modules.
So it has to single combination of voltage timings and frequency that need to be good enough for both.
Memories has profiles loaded for voltage, timing and depending of the current memory frequency.
You can always go into the bios and play with the settings to find the optimal for both.
Here's an example:
So this is ddr4 3000 but it can work at 1066 and 1400 and has timing and voltage assigned for those.

You can start by putting all four memory modules together and check the parameters with Cpuz.
And run some memtest and/or Prime95 to make sure its stable.
If it fails we can get into tuning timings, voltage and freq.
