yes you can.
Get a "y" coupling for whatever size duct you need

Absolutely not. The damper in a bathroom fan generally is not strong enough to stop the positive pressure that would be present in the range duct when it is running, so you could have range exhaust venting to your bathroom.
Both the range hood and bath vents have specific limitations as to the length of the duct. Each fitting adds several feet to the calculation. An added T fitting may push you over the limit.
This strikes me as something that would be a code violation, but I don't have time to search right now. In any case, common sense rules it out.
As for venting to the attic, again an absolute no. I know that you did not suggest this, but someone else has. The reason for a bath fan is to eliminate moisture from the home, not so much an odor control thing. Venting to the attic does not get it out of the home, just moves it to a different place that is often a moisture problem anyway. That would absolutely be a code violation.
Your bath vent needs to vent to the outside. Either through the roof or through the wall. A hood for the wall is less than $10, roof is a bit more but still under $15. Trying to get by with something less will cause you some problems in the long run.

I would agree with Mark in NOT doing it as you may get some backdrafting that you will not like and the hood fan sends grease vapro out which you dont want back drafting into your shower...
They do make connector pieces that have plastic anti-backflow flappers in them that you could install in the stack before the connection on each pipe (therefore needing two) and that would help you on that aspect but over time the grease will build up on the flapper valve and make it stick open or closed...
I would not recommend just venting it into the attic space as that is a code violation in pretty much every area of the united states. IT will hurt your resale value... It could give you mold or rot problems (warm and wet) or freezing and wood damage issues (cold and wet).
Vent it out through the roof or run the flexi pipe to another shower vent stack...

why just duct the exhaust fan into the attic space if you are bold you can duct it tho the roof with a stack I would not do that as the range hood fan will cause a back draft thro the bath fan

Do not do this. When one fan is running, you will get odors from the other unit. The moisture from the bath will also come out at the range. Ending a bath fan into the attic is against codes and will cause a major mold problem.

I would agree with Mark on the backdraft. You might be making breakfast and smell someone in the potty, would you want that, I think not.
Give it, it's own space while your at it.

If you are mechanically talented go for it. It should cause no danger to the house.
