If anything with a keyboard is considered to be cousin to the piano, then an organ and an accordion are both cousins to the piano. If the method of creating sound from that keyboard is the measure of an instrument being cousin to a piano, then the hammered dulcimer, the clavichord, the harpsichord, and even the celesta would be cousins.
for a cello it would be a violin for a piano it is a guitar.
The highest note on a grand piano is the note C. The lowest note on a piano would be D.
Depends on the model and condition it's in. Do you know the serial number? From that you can determine the date. If you measure the piano, then you will know the size and can determine the model.
