Answer 1

If you look at our Solar system, it was initially a gas/dust cloud. Then stuff began converging in the middle, forming a heavier blob of gas/dust, which through gravity attracted more gas and dust until it was massive enough to ignite into a star. And far away from the star gas and dust grouped into smaller blobs that eventually formed planets.

If you scale up to the bigger space, you have the same gas/dust clouds, some smaller and some bigger. If put close enough together, gravity will pull them all towards some center of mass. But within each cloud stuff will be clumping up and forming stars. And now you have a bunch of stars being formed in a cluster.
