During the new and full moons, the gravitational pull of the Moon and Sun align, causing higher high tides (spring tides) and lower low tides (neap tides). This alignment results in more extreme tidal fluctuations than during other phases of the moon.

On average, one seventh of the full moons occur on a Friday.
Solar eclipses only happen on New moons when the moon is exactly in orbit between the Sun and the Earth.

Yes, it does in deed have full moons and new moons. One or the other appears every 14.77 days.

The question is a little vague; I'm going to assume you mean full moons. The synodic period (the time between two full moons) averages 29.53 days, which works out to about 12.4 of them per year. In any given calendar year there are either 12 or 13 full moons. 2014 is a "12 full moons" year; 2015 will have 13.
"Spring" tides, which are a little higher than average, occur at new moons and full moons. "Neap" tides, a little lower than average, occur at the quarter moon phases.
No. There are two New moons, on the 1st and 31st of the month,and one Full Moon, around the 16th and 17th.
