You will be disqualified for handing in a card with the wrong handicap. That is what the rules dictate should happen, if you are given a card with the wrong handicap on it, you should change it.
No. Different coloured tees on the same course have different handicap ratings, so the handicapper would be unable to handicap you based on that round.
A handicap allows all golfers to play on a level playing field. It is an allowance of strokes per round. Say a player has an 18 handicap, and shoots 88 on a par 72 course, their net score is 70, so they are two strokes better than their handicap, and had a good day. It also allows two players of different abilities to play against each other. Say a scratch player (0) played an 18 handicapper, the scratch player would give the 18 handicapper a shot a hole. So if the 18 handicapper made a 5 his stroke reduces it to a 4.
honestly i would have to say that that is not a bad round of golf unless you are a like single digit handicapper then that is a very very crappy round...
You don't need to achieve any handicap to turn pro. A 28 handicapper or a +5 can. To become a teaching pro you need to pass a playability test, which is two rounds and you have to shoot under a certain score, it varies from location to location but it is a few over for each round. There are also written tests etc. To be a player, you just need to qualify and try and win your card.

If you mean when you are collecting three cards for a handicap then no. If you mean during a competition round then yes, unless they do not complete the round, in which case another playing partner must continue marking.
No, that round does not count. It will not affect their handicap in anyway.
In tournaments, at the end of the round it is added to the final sanctioned score.
In golf, a player's handicap reflects their potential ability, which is typically based on their scores relative to the course's difficulty. A better inward half (the last nine holes) can indicate improved performance, often leading to a lower score and a better overall handicap. However, a player's handicap is calculated based on their best scores rather than specific halves of the round, so while a better inward half can contribute to a lower score, it doesn't directly impact the handicap unless it results in a qualifying round.
Neither. A golfer applies his or her exact handicap index to a formula which determines their course handicap for the specific course and set of tees that they're playing. The course handicap for each competitor is used. Those are expressed in whole numbers so no rounding is involved.
Make your own odds! How good are you? Your handicap reduces with every good round. It would be hard work but you can do it if you work at it.
