State and local building codes will tell you for your area, but, I would use no smaller than 3" to tie in everything.

Can I place a shower where a toilet currently is and visa versa and are waste sizes the same and if so can I connect new stack to existing in attic?
The toilet is 3 or 4 inch and the shower is 1 1/2 or 2 inch. You could reduce the toilet to 2 inch, but it would never flush correctly or be of much use. The current toilet drain has no trap in that section because one isn't needed. The toilet itself is the trap. If you are using existing waste lines, they should already be connected to the vent stack. If you are adding lines, connecting to the existing stack is fine as long as it is above the last drain.

Can the drains for a shower and sink come before the drain for the toilet Example the sink and shower then comes toilet then enters main stack?
In my experience I've seen this type of scenario in older buildings. Usually the sink will tie into the stack in the wall while the shower generaly connects in below the toilet also known as the closet bend. In alot of older houses and apartment complexs they have tied multiple drains together in a smaller pipe before going to a larger one. For example the lav with the tub, the kitchen sink with a tub, or all three together.

Double-stack system in drainage?
A double stack system is where you have the main soil stack to carry away toilet waste (Generally). With a separate pipe taking waste water from a Shower/Bath/Basin to an outside gully leading to a sewage drain (maybe via guttering on your property). Not a common system on new builds but still found on pre 60's plumbing.
Can the roof venting of a toilet be upstream of the toilet flange?
Most of the time they are. Depends on how far of course. Usually, the toilet is by the main stack so it only has to go the 12 to 16 inches to get to the drain. The main stack goes through the roof for the vent for the whole house or the bath and laundry. As long as the toilet is getting venting from somewhere, it should still flush.
Can a wye be added for a shower below the vent on the water closet stack?
Yes, BUT check your local code to be sure
How can you tell if its a vent stack problem when the toilet will not empty?
The toilet will gurgle as it sucks air through out the toilet trap. You may even hear it suck air through a nearby sink or the tub. Sometimes it may just drain slow or weak.
