Answer 1

A word template that fits nicely here is:

B*LL, giving us BALL, BELL, BILL, BOLL and BULL.

And the words can be used in the following order:

Mr. BILL BULL, a farmer, experimented with a new process to turn the BOLLs from his crop into BALL or BELL shapes.

The farmer's surname can even be considered pleasantly appropriate considering his occupation :)

D*CK, giving us DACK, DECK, DICK, DOCK and DUCK.

And the words can be used in the following order:

Mr. DICK DACK, a farmer, experimented with a new process to turn the DOCKs from his crop into DECK or DUCK shapes.
