BRIC countries are just clumped together for being developing economies that are going through similar experiences, but it is far from being a political-economic group.
Correct, but I wouldn't say this can be called an "Alliance". Even the members of this group are hard to precise. Some would put Korea, some would put Nigeria, some would put Indonesia, etc.
"BRIC" is no NATO, or anything that resembles some formal structure. The "BRIC" countries are getting into multi-lateral agreements, yes, but there is no "BRIC" organization. While the summit is used to conduct agreements between Russia and China, or Brazil/China/India, there is no "BRIC alliance".

Quite the opposite, actually.
