Angles are a thing. Use them.
The great tragedy of lighting -- up until LED -- is that every bulb emits a sphere of light. That is fairly useless. Everyone wants a wedge of light to illuminate whatever they're trying to light up. Refelectors try to put some of that to use, but reflectors don't perform well.
If you've ever seen one of those metal halide barn lights, half their light goes to wildly overlight the side of the barn they're attached to. What's the point of that? It is wasted light!
The advantage of LEDs is they naturally light about a 160 degree wedge, and it's easy with lenses to focus that much more narrowly. Lenses are much more efficient than reflectors.
So you've given us a horizontal diagram, now you need to diagram this out in the vertical dimension. What is below the lights? What wedge of light do you want from each lamp? The angle of the wedge is the angle of the lamp to buy.
For instance, a 60 degree light will spread to create a circle about the same diameter as its height above the surface. (Well 1.15x to be precise). And half that as their radius. So some of your lamps are 900mm (3 foot) away from the wall: if you wanted to light the floor, and the lamps are 2.2m above the floor, then the disc of light will be about 2.2 metres in diameter, or 1.1 in radius, slightly bigger than their distance from the wall. So a 60 degree light there will light the floor effectively, and waste little energy lighting up the wall.
Whereas on those lamps 300mm from the wall, they will throw a lot of light on the wall even with a 60 degree light... unless they can be aimed away from the wall. It would help a lot if they were lighting up a surface much higher than the floor, like the top of a row of dressers, maybe with a mirror.
