How to write two, three, ten, business, money, appointment and Jia in calligraphy?

Your question is not accurate.

That depends on what font is written.

When writing a signature on paper, it is often more lettering.

(mostly used for year numbers. )

Ren, Jia, Qian, Shang and so on. You can look at the picture for reference.

I only have a marker in hand.
