Mr. President
President Kenneth Kaunda was the first and former president.
The correct title for a former president of the United States is "former President."
You should describe a former governor as "...the former governor of (state)", but when introducing a former governor you should say "...to introduce Governor XXX." Like a former judge, general, president, senator, or other public official, a governor retains the title after leaving the office.
No- but he can ask somebody in Congress to introduce a bill for him .
I think the former President will appoint the vice president I think the former President will appoint the vice president
The U.S. President cannot introduce a bill, but it is part of his/her job to suggest to Congress what bills are needed.

Ulysses S. Grant was a former Union general who became president.
An ex-president is a former president - a president who has left office.
Only members of Congress con actively introduce bills.
