I'm quite confused with the prepositions when used for destination(s) as in below. Could you teachers please point out the correct one in each sentence.

Where can I catch a bus to/for Boston?
Where can I catch a bus to/for downtown?
Where can I catch a bus to/for the airport?
-------------------
Where is the bus to/for downtown?
Where is the bus to/for Long Beach?
Where is the bus to/for Battery Park Station?
-------------------
Is this the right place to catch the bus to/for Oxford Street?
Is this the right place to catch the bus to/for The Gardens Mall?
Is this the right place to catch the bus to/for Park Avenue?

Is this the right bus to/for Oxford Street?
Is this the right bus to/for The Gardens Mall?
Is this the right bus to/for Park Avenue?
-------------------
Does this bus stop at/in Times Square?
Does this bus stop at/in Greenwich Village?
Does this bus stop at/in Chinatown?
Does this bus stop at/in downtown?
-------------------
Much Obliged, Thank you.

All of your first sets of sentences are OK. Changing the first part of the questions does not affect preposition use.

And these are correct:

Does this bus stop at Times Square? ( a point location)
Does this bus stop in Greenwich Village? (an area of NY)
Does this bus stop in Chinatown? (an area)
Does this bus stop downtown? (an area, but idiomatically no preposition)
