According to this (https://en.m.wikipedia.org/wiki/List_of_objects_at_Lagrange_points) there are currently about 6 satellites at L1 and 5 more planned to be put there.
I don’t understand how they don’t collide with each other since the closer to the centre surely the less fuel needed to stay at L1.

All of the Lagrange points are, obviously, points in space, but you don’t have to be precisely on the point to get the lion’s share of the benefits of being close to the points.
Additionally; L1, L2, and L3 aren’t totally stable, so you’re going to need to expend fuel anyway to nudge yourself back to the point every now and again.
