Stock Market? - stock market ticker symbols

Hello, I'm 19 and I wanted to learn more about the stock market and how it works.
On the stock market right now and all these things that really dont understand, in the hope that someone could tell me what this means everything?

Last $ Hotel Reviews - 27.87
Volume - 45216569
Change - $ 0.12
% Change - 0.43

Knowing all this can someone tell me what does all this mean to tell me if I own the stock of money they have done?

Thank you in advance.
