There is no assigned number, exemptions are given for PGA Tour wins, past champions, world ranked top 50 etc so it varies each year. Low 90's would be an average field size.
The players' numbers mean nothing except to the players. The players get to choose which number they want to wear.

What rank the player is in the world or most likely the tournament. This is chosen by how good their world ranking is. They also take into account past performance, as well as how good the player is on the surface - e.g. in 2005, Andy Roddick was ranked lower than Lleyton Hewitt, but he was seeded 2nd ahead of Hewitt (Federer was obviously seeded first), due to his success at the tournament the previous year (reached the final), and his success on the grass courts at Queens. Seeded players earn a 'seed number' by having a high ranking/good record. The seed 'number' is awarded based on the expectation (usually based on rankings) which indicate how the player might perform in this tournament. The 1 seed would be expected to win the tournament and is usually the highest ranked of all the players in the tournament. The number of seeds in a tournament depends on the number of competitors.
The cut for the Masters is determined by the top 44 and ties, and those withing 10 shots of the lead. This is an individual rule as determined by the masters, there is usually a bigger field in PGA Tour events so a larger number of players make the cut.

The number of players on a soccer team, any age group, varies. Most people will say about 17-18 is a safe number. You have 11 starting players and 6-7 substitutions. This way if a player is injured, sick, or unable to make a game or tournament there are still enough players to take part in the game. You always want to have at least 3 subs.

Rankings are subjective. The NCAA Tournament games are about matchups.
