I am wondering if I need a comma in these sentences?
1. Walking the street one Sunday morning he saw a tall woman walking with two large dogs.
( Do I need a comma after "morning"?) Yes, you do need. When the sentence starts with a non-finite clause, you put a comma after it.
2. Finally he could breath freely. After a long and exhausted march, which took him hours to finish, he arrived in the town.
(Do I need a comma after "Finally"?) No, you do not necessarily have to. You can, though.
3. He was an old man but still nothing could prevent him to compete in the competition.
Without a comma. "But" is a coordinating conjunction, but in this context, it joins two elements of equal syntactical importance.
4. After consuming all stocks of food they had nothing to eat for days.
(Do I need a comma after "food"?)
yes, when you start a sentence with a subordinating clause, you put comma after the end of the clause.
5. She was working hard all the time but the results were meagre. Finally she decided to give up and find another job.
(Do I need a comma after "time" and "finally"?)
after "but" yes, after "finally" no
