Trying to identify what is what. I originally thought the 3.5" by the wall was Toilet, but i don't think 5" away from "unfinished" wall is enough space. So the other 3.5" (2) must be the toilet? What is the other 3.5"(1) then. My guess on the others are (3) Shower and (4) vanity?
-Thanks for any advice.

1 is a spare stack and it's 3" abs
2 is the toilet also 3"
3 is a vent and
4 is a sink.
It's a pretty bad rough in. If 3 is in fact a vent why is it so far away from the wall? If it's for a shower/tub why is it so close to the wall?
This is what your rough in should look like
3 must be a vent.
EDIT This is an example of what is going on

If you can pour water down one of the 2-inch pipes and see that it holds water at level, that would indicate it has a trap as in the pipe at the far left of the image. Traps it only ever be installed at floor drains or shower drains it sink drain will not have a trap under the floor.
Your 3-inch that's close to the wall may be repurposed as a shower drain provided it's vented.
In your image pipe number 3 could very well be intended as a shower drain, just in a very poor location.
