What is the difference between vernal and autumnal equinox?
The adjectives vernal and autumnal mean "of spring" and "of autumn (fall)" respectively. The equinox, when the day and night are even, occurs twice a year. Once in spring and once in autumn (fall) as we move from the extremes of the summer and winter solstices. Therefore we have a vernal equinox (in spring) and an autumnal equinox (in autumn/fall).

What is the term for when days and nights are equal in length?
The word is "equinoctial" = equal day and night. It occurs twice a year, on the first day of Spring, and the first day of Autumn.
Does the autumnal equinox mark the beginning of fall for both hemispheres?
That is depending on what you regard as the autumnal equinox. The autumnal equinox in the northern hemisphere is in September and it marks the start of autumn. In the southern hemisphere the autumnal equinox is in March and it marks the start of autumn. So looking at in that way, you can say yes. Of course those are two different dates on the calendar, so the autumnal equinox in one is happening at the same time as the spring equinox in the other. It is the same equinox, but where on Earth you are, determines which equinox it is. As autumn starts in one hemisphere, spring is starting in the other. So on that basis they don't mark the start of autumn in both hemispheres. It is never the same season in both hemispheres.
What is the Fall equivalent to the Spring Equinox?
Spring equinox occurs around March 20 and Fall equinox occurs around September 22 for the Northern Hemisphere. For the Southern Hemisphere these dates are opposite; the Spring equinox is around September 22 and the Fall equinox occurs around March 20.
What is the difference between summer solstice and equinox?
The solstice is day of the year with the longest period of light (the summer solstice) or the longest period of night (the winter solstice). The vernal equinox (spring) and autumnal equinox (fall) are the two days in the year in which the periods of light and periods of darkness are exactly the same duration.
