afaik there is no way to really share uv’s between different objects. they might share the same projection support, but each still has it’s own UV set, and as soon as you freeze the projections there is nothing common between them.
If I understand what you want to do correctly, I would do it like this: combine per 4 objects ( the 4 textures each take one quarter of a new combined texture, layed out in a 2 by 2 grid) or per 9 (l3 by 3) or even one bigger one and 5 smaller ones (based on a 3 by 3 with squares 1,2,4 and 5 combined into one – if you get what I mean) It’s easy to combine the existing textures like this in photoshop. In the texture editor you can achieve the same layout as well, by transforming the UV’s. There is a “set” icon somewhere, uncheck it – now you can type in a formula in the value boxes for the uv’s, for instance first: “ 0.5* “ to scale by half and then “ 0.25- “ to offset to one corner. Do this for U and V for each UV layout – and you end up with the unwrapped UV’s you had, and now they can share a single texture.

Is there an easy way to create 1 material with the 3 texture combined in 1 texture and 1 uv? c
