There aren't any specific patches you have to have when you first start Girl Scouts. Your troop leader, adviser or guider should either purchase them for you or give you a list of the insignia you should buy.
For Girl Scouts of the USA (GSUSA), you might be asked to purchase the council identification patch and the troop numbers.

As a brownie in girls scouts a group of girl s earn patches by doing different activities. These activities are to broaden a girl's horizon about the world and teach them new skills. Before being a brownie, a girl can be a Diasy, and after being a brownie they can be a junior.
Girl Guides and Girl Scouts began in several countries at about the same time that Boy Scouts were getting started. Girls wanted to be Scouts, too. Eventually, Lord Baden-Powell decided that girls should have their own organization, so he asked his sister, Agnes Baden-Powell to help start Girl Guides. They officially founded the Girl Guide movement in the United Kingdom in 1910.
Juliette Gordon Low started the first troop of Girl Guides/Girl Scouts in the United States and is considered the founder of Girl Scouts of the USA (GSUSA). Before Juliette brought Girl Guiding to America, she also helped start Girl Guide troops in London and Scotland. Juliette also helped found the World Association of Girl Guides and Girl Scouts (WAGGGS).
At the time when Boy Scouts and Scouting were getting their start from Robert Baden-Powell, girls became interested in what the boys were doing and said they wanted to be Boy Scouts. Robert Baden-Powell thought that girls should have their own organization, so he asked his sister to help start Girl Guides. The organization is known as Girl Guides in some places and Girl Scouts in others.
