It just occurred to me that you might mean "traffick" as in "to move drugs." If so, the past tense is "trafficked."
There is none. "Traffic" is a noun (a person, place or thing) NOT a verb (showing action
or being).
It's not a verb because you can't "traffic"....it's not something you can DO.
Only verbs can have tenses (past, present, future).
stuck. it is in the form of 'he was stuck', not 'he is stuck.

The word "were" is past tense. It is the past tense of the verb "to be."

Existed is the past tense. The past perfect tense is had existed.

HAD is the Past Tense of TO HAVE.
