    I believe you will find the minimum size is 3", 4 would be better.

    Not sure I 100% understand your question... but...

    Yes, you can have 2" floor drain. Make sure you install trap as well

    Yes, you can connect floor drain pipe to an existing toilet drain - but I highly suggest you vent and prime this floor drain

    No, you cannot use 2" drain for toilet

    Hope that covers it all

    Maybe I missed this but the 2" is a drain, not the toilet drain. Maybe you can better describe what you have and want.
