Question: Do you think that humans associate humans with certain emotions and feelings based on past experiences?

Yes I think they do! The emotional centre of the brain (the amygdala) adds an emotional value to someone and transfers that value to the area in the brain involved with forming memories (hippocampus). This is also integrated with features of the person in question: their face, smell, their voice. All this separate information is integrated in the hippocampus to form a full snapshot of an interaction that can be recalled when necessary.
Your perception of someone you meet for the second time is based on that known information. The information that is sent back to the hippocampus for memory recollection (remembering someone) but it is biased to what was more emotionally resonant. However your perception changes over time and so can the emotions you feel when around someone.
