Can't be done.
You can only split networks in half, so you can have:

128 addresses (126 usable) 
64 (62 usable)
32 (30 usable)
16 (14 usable)
8 (6 usable)   
8 (6 usable)   <---- put your 4 here

But now you're looking at 6 subnets, which isn't what you want.

Don't know of a way round this , and you're looking at connecting all those
separate subnets with a lot of networking kit.

So basically, find another solution that doesn't require 4 Ips on
their own subnet. How about 128 on their own subnet?
