Does it matter what side of the radiator the bleed valve is located on?

The radiators are distributed via a manifold, with separate supply and returns.

Supply bottom right. Return bottom left.

My issue is that a few rads bleed valves are too close to a wall making bleeding a bit cumbersome,

    Bleed valves are usually located on the opposite side of the water inlet.

    But as long as it is high it doesn't matter much as long as you have good air elimination or management in the system. Once it is circulating the system should be designed to eventually get it to the boiler and vent it or put it in a compression tank.
