The second questions is: Does a cell site is used by many cell phone service
providers
TIA to satisfy my curiosity! ;-)

Yes, it's a cell site. It's the pretty standard 'three sector' arrangement:
There are three 'sets' of antennas, each covering 120 degrees. In each set
there are usually three antennas: Two that receive (the signals are combined
in a form of diversity reception), and one that transmits. It appears that
your tower has the transmit antennas below the receive antennas, but I
couldn't really say for sure.

You can also see a couple of covered microwave dish antennas that are
probably being used for site to site (point to point) links to other small
cell sites, a large hilltop repeater, etc.

Typically, yes -- one company will build a tower, and the other carriers
will rent space of the unused space on it. On the other hand, I've seen
cases where you have 2 or 3 towers within a few hundred feet of one another
because the companies apparently couldn't come to a leasing agreement!

Some of the cell phone companies have maps of their tower locations -- some
even with pictures! Sprint's is here:

That would make more sense then vice-versa, correct? The received
signal is coming from your low-power cell phone, and you'd want a good
line-of-sight in order to overcome any transmission power shortcomings.

However, you can transmit from the tower at a much higher power than
your cell phone can, so you're not as worried about being lower and can
overcome minor LOS shortcomings with brute power, which you can't do
with a cell phone.
