Can the supply and returns 90 degree immediately after leaving and entering the close spaced tee into the secondary loop?

It's fine if they're on the side branches of the tee (since there is already turbulence from turning the T corner), but to achieve reasonable hydraulic separation it's best if there is at least some straight pipe both before & after the tees on the long axis. The tried & true rules of thumb for this type of hydraulic separator are defined here:
The naming convention is somewhat arbitrary as to which is considered primary and which is secondary, but for this to work well the high-turbulence loop at the tee connection should only be one or the other.

The closely spaced tees only make it so one pump doesn't affect another pump. The water jets passed the tees like they aren't even there.
The branches don't care how they are configured. Only the pump will care. You'd like the secondary pump to easily grab/inject water from/into the tees. The less 90's the better. Especially very near the pumps suction side.
