From your screenshot I see 13 registers:

AX = 0000
BX = 0000
CX = 0000
DX = 0000
SP = FFFF
BP = 0000
SI = 0000
DI = 0000
DS = 0DAB
ES = 0DAB
CS = 0DAB
SS = 0DAB
IP = 0100

Each register has 4 hex digits, i.e. 16 bits wide.

A byte is 8 bits long.
The size of a word depends on the definition used for that particular processor and its architecture.
