There are 2319 clubs in Ireland. All of these would be very different in size. So it is very difficult to know for sure as to how many actual members there are. Total membership would run into hundreds of thousands of people. In addition there would be many people who would follow the sport and attend matches but not be a member of a club.
All 32 counties have Gaelic Football and Hurling teams. Counties have lots of levels in terms of ages and ability, so each individual county would have lots of county teams, from senior teams down to children.
Metropolitans is said to be the first club founded, but it is no longer in existence. The oldest existing clubs are Round Towers in Clondalkin, founded in December 1884 and Faughs, now in Templeogue, founded at Easter in 1885.
Every county and club that are part of the GAA have their own colours. Many colours in different arrangements are used for the shirts of the clubs and on their flags. The GAA itself does not have any specific colours. It changes its image every so often. Its current logo is blue and white, but they would not really be said to be the GAA colours.
Helping the lowest levels of the GAA in terms of the clubs and their facilities. This is the base of the GAA. The network of clubs, over 2500 in Ireland alone, are where the GAA derives its strength. It is built on the clubs. They are the root of the organisation. The ordinary people that run these are what make the GAA what it is, so it is important to support them. So a lot of investment goes into the clubs to help them as they are the grassroots of the GAA. Without the clubs the GAA would not exist, so money earned within the GAA is needed to keep them going.
That would be an impossible task. There are over 2500 clubs in Ireland alone, and hundreds more overseas. Consult the GAA website below:

No. GAA clubs welcome all members of any nationality. The GAA is an Irish organisation and it is found around the world where there are large groups of Irish people, so members are mostly Irish, but there are many members that are not from Ireland.
It is hard to give a definitive answer as it can change, but it is well over 100. Many clubs and regions have websites. See the links below for some useful links.
Adding together Hurling and Gaelic Football titles won in all grades, Cork would be the most successful county in the GAA. As to which county is the best, that is a question that could be debated by many people.
Ballinahinch GAA Club in county Tipperary was founded in 1886.
You cannot play GAA. The GAA is an organisation, not a sport. It governs a number of sports including Gaelic Football, Hurling, Camogie, Handball and Rounders. The rules of those sports are all different.
