What kind of code are the markings on the resistors in the picture?

I think they write out the Omega symbol, just because there is enough space on the component and looks nice, but I was not able to find any matching result online about the meaning of the letter 'F' and 'J'.

What kind of marking system is it?

One likely option is tolerance code. F = 1% and J = 5%.
