The requirements of the Scrum are vital in toady's union code. The platform it provides for stages of play are more strategic than ever. Ive attached a site address used by coaches as it has text and graphics to illustrate the requirements and makes more sense than trying to explain in here.

John Spalding did play scrum before Micky Booth at Gloucester.
There are 3 rows in a league scrum the same as union. However, the 2 wing-forwards (flankers) have been removed from the league game.
In the union code 8 players from each side form the scrum. In the league code its 6 players from each side (league do not have flankers)
technically I believe No you cannot add players to the 3 rows that are defined as the scrum added to this is the fact that a contested scrum cannot take place unless the front row contains the trained props and hooker.
scrum-half
The loose forward that packs down at the back of the scrum is called the 'number eight'. Sometimes this position is called 'back rower' or 'last man down'.
The ball is put in the scum in the loose head prop side in both codes (number 8 in league and 1 in union)

No it is not, it is still play on or anyones ball
There actually IS a scrum half in the Union Code - Playing with number 9 on their back along with the no 10 the fly-half they are jointly the Half Backs In league the scrum half wears 7 with the stand off (- fly half) wearing 6. The numbers start with the loose head prop in union (1) and with the full back in league (1)
The Scrum Master is one of the most important elements of Scrum Teams success. The Scrum Master does whatever is in their power to help the team succeed in their attempt at building the product. The Scrum Master is not the manager of the team; instead, the Scrum Master serves the team, protects the team from outside interference, and guides the team's use of Scrum. The Scrum Master makes sure everyone on the team understands and follows the practices of Scrum, and they help lead the organization through the often difficult change required to achieve success with Agile methods. Since Scrum makes visible many impediments and threats to the team's effectiveness, it's important to have a strong Scrum Master working energetically to help resolve those issues, or the team will find it difficult to succeed. Scrum teams should have someone dedicated full-time playing the role of Scrum Master. In case of smaller teams, the same scrum master could play that role for multiple projects.
