so nanohertz is one wave per 10 years?

1E-9 cycles/second <--> 1E9 seconds/cycle

Figure 3.2E7 seconds/year so this translates to ~32 years/cycle

Is it wrong to assume there's many other wavelengths of these waves?

No, they come in a wide range of frequencies/wavelengths depending on the systems under study. LIGO is sensitive to a higher frequency/shorter wavelength range. LIGO can't access Nanograv's regime due to limitations on reducing environmental noise.
