The next year Christmas day will fall on a Tuesday is 2018.
No, Christmas, 2018 is a Tuesday; Christmas, 2019 is a Wednesday.
No, in 2018, Christmas day falls on a Tuesday.
This is variable, it depends on the way leap years fall in between any two given years. For example, Christmas of 1990 was a Tuesday but because of the occurrence of the leap year in 1996, Tuesday got skipped over and didn't occur again until 2001. However, since there are 2 leap years between 2007 and 2012, there is as few as five years between 2 Christmases falling on Tuesday (one in 2007 and this coming Christmas). Between the year falling after a leap year and six years later (e.g. 2001), since there is only one leap day between these years (2004), the Christmases of 2001 and 2007 were both Tuesdays and similarly, since there is only one leap year in-between 2012 and 2018 (2016), Christmas 2018 (six years later) will fall on EXACTLY the same day of the week as it will in 2012 (bear in mind that the 2018 calendar will not match exactly with a 2012 calendar, as 2018 only has 365 days, whilst 2012 has 366 days).
The next Christmas that falls on a Tuesday will be in 2012. The next one after that will be in 2018.

As of 2016, Christmas Day was last on a Monday in 2006. It will next be on a Monday in 2017. An 11 year gap is common, caused by days being skipped over by a leap year. It was on a Sunday in 2011, but skipped Monday in 2012 and was on a Tuesday, as it was a leap year.
31/12/2017 to 24/12/2018 = 365 - 7 = 358 something like that New Year's Eve to Christmas Eve
It is this year - Thursday 1st March 2018
2001, 2007, 2012, 2018, then the 11 year gap 2029, 2035, 2040, 2046, then the 28-year cycle repeats itself
Yes, the next one is in 2018.
