I'm from Texas, and I don't recall either of these: pie(Spanish for foot) and vara (Spanish for rod) The vara was a surveying term.
According to the related links, 1 pie = 0.925853018373 feet. and there are some discrepancies in the vara (it varied from place to place).
One site I found a vara = 33 1/3 inches, but another stated 33 1/2, but went on to say that 36 vara = 100 feet, which corresponds to the 33 1/3 value, so that should be it (for Texas anyway). With this measurement of 33 1/3 inches, 3 pies = 1 vara.
There are thousands of measurement units in both systems and it is not possible to list them all.
The "metric system", more precisely the SI, has lots of units, depending on what you want to measure. Check the Wikipedia article on "SI units" for a list.
Strict adherence to SI units would force you to use m3 (meters cubed) for any volume measurement. Common practice, however, would use the liter (L) for liquid volume, but this is not strictly adhering to the SI system of units. A good list of different units may be found: http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch1/units.html#si
In the metric system, kilograms per cubic meter (kg/m3) are used to find density, though other units, such as pounds per cubic foot are also used. For a complete list of units used to find density, visit the Related Link.

Nga-nga ! Hahaha xD
How many UNITS of measurement? Too many to list here.
There are not three, but seven base units in the SI. See the list here: http://en.wikipedia.org/wiki/SI_base_units The first three in the list are the ones used in mechanics.

There is no list of household measurements, so a systematic list is not possible. Lengths, masses and larger volumes are measured in standard (SI) units. For smaller volumes: 1 teaspoon = 5 ml 1 tablespoon = 15 ml

One can find a list of cities in Texas on the Texas government website. Such a list is also available on the Wikipedia page for Texas. Google Maps may also be a helpful source as it offers the names of cities, but not in the form of a list.
None of the units on the list you provided with the question has any name.
