I’m having trouble with calculating the energy of $pu5.00e10$ photons of frequency $pu1.00e9 s-1$.
I know that to calculate the energy $E = hf$ is to be used. However, I am unaware as to what to do with the $pu5.00e10$ value and its meaning.

Analogy: you have 5 bottles of coke 1 L each; what is the total volume?
The formula you shown $(E = hf)$ is derived for exactly one photon.
Now, since you have 50 billion of photons $(N = pu5.00e10)$, guess what total energy it would be?
$$E_mathrmtot = Nhf = pu5.00e10cdotpu6.63e-34 J scdotpu1.00e9 s-1 = pu3.32e-14 J$$

How about if I am given instead of a frequency value a wavelength value along with the photon value, how do I answer solve for the energy.

For the speed of light do I use c= 3.00E8 and if I do, do I use the frequency value gained to solve for the energy?

Yes, you do, but mind the units. If you take $c = pu3.00e8 m s-1$, then make sure you plug in the wavelength in meters.
