In brief: Nail fungus spread

Since nail fungus is spread by direct contact, it is very likely that this can spread from one nail to another especially on the same foot.
When treating nail fungus, i recommend treating all nails. Healthy nails should be treated in addition to the infected nails in order to prevent spread of the fungus.

In brief: Yes

Chronic contact with someone who has a nail fungus is a risk factor for transmission of the fungus, however, the greater risk is having a concominant disease like tinea pedis (athlete's foot), psoriasis, diabetes, and other immunodeficiency diseases.
The key to prevention of spread is to ensure that showers and baths are freqently sterilized and that footwear is kept clean and dry.

In brief: Yes

Any nail fungus on one nail can spread to other nails if untreated.
Furthermore, it can spread to the skin as well.
