The simplest way is to click directly on the ruler at the point you want to set a tab. You can also do it through the tab settings and type it the measurement that you want to set the tab at.
You can click on it and drag it off the ruler, or you can delete it through the tabs dialog box.

These are tab stops. In Microsoft Word you can create a tab stop by clicking and dragging on the horizontal ruler, where they appear as flipped-over black L or T marks. If there are faint marks below the ruler at 1-inch intervals, these are the default tab stops.

Tabs can only be created on the ruler. You could put a tab at the very right end of the ruler, but it would be easier to just right align the text. Tabs are for setting positions that are not at the absolute left, right or centre of the page. That is what alignments can do. So it would make no sense to put a tab at the extreme right or left of the ruler.
Use the Insert tab and select from the Charts section.
The custom tab marker is different for each kind of tab, so for example a left tab marker looks different to a decimal tab marker, so in this sense they will indicate the alignment that would be implemented if the tab key is pressed and the tab is used. If the tab is not used, then it does not indicate what way the text is aligned.
Dragging on the tab stop on the ruler will move text that is aligned with that tab. If it is a single line, it is enough to have the cursor in the line of text, without selecting. For multiple lines or paragraphs, select the text.
The "Insert" tab.
