There's is always going to be a median. Never is there not going to be a median.
the median and mode are but the mean is not
when is it appropriate to use arithmetic mean as opposed to median
No, the median is not always one of the data values. In a dataset with an odd number of values, the median is the middle number, which is a data value. However, in a dataset with an even number of values, the median is the average of the two middle numbers, which may not be a value in the dataset itself.
It is easy to get a median with an odd amount of numbers, as there will always be one number in the middle of the list. So, for example, if you have 7 numbers, n1, n2, n3, n4, n5, n6, n7, the 4th number is always the median, so n4 would be the median value in this case.
Yes, the median is always a number. For qualitative data, use the mode for a measure of center.

the median and mode are but the mean is not
No, not always. Median is the number that's in the middle of a group of numerical data. Mean is just the average of a set of numbers, which isn't always in the middle.
The median is the 50% percentile.
yes
Yes.
No, the median voter is not always the voter with median income. The median voter theorem suggests that in a majority-rule voting system, the preferences of the median voter will dominate, but this median voter is determined by political preferences and positions rather than income alone. Factors such as ideology, age, education, and other demographic variables can influence who the median voter is, meaning that the income distribution does not directly correlate with political preferences.
