Here are the completed statements:

a) The smallest whole number is $\boxed{\text{0}}$.

b) There is $\boxed{\text{no}}$ largest whole number.

c) In whole numbers, $\boxed{\text{0}}$ has no predecessor.

d) The predecessor of the smallest 5-digit number has $\boxed{\text{4}}$ digits. * The smallest 5-digit number is 10000. * Its predecessor is $10000 - 1 = 9999$. * 9999 has 4 digits.

e) The successor of the greatest 5-digit number is $\boxed{100000}$. * The greatest 5-digit number is 99999. * Its successor is $99999 + 1 = 100000$.

f) The smallest 7-digit number ending in 5 is $\boxed{1000005}$. * The smallest 7-digit number is 1000000. To end in 5, the last digit changes to 5, making it 1000005.

g) 387 is to the $\boxed{\text{left}}$ of 388 on the number line. * Since $387 < 388$, it is to the left.

h) 4397 is to the $\boxed{\text{right}}$ of 4396 on the number line. * Since $4397 > 4396$, it is to the right.
