You would be 2nd cousins....or your great uncle. you would be a great niece or nephew. Now if you didn't know the answer to your own question, you wouldn't be a very great niece or nephew ! :/
The complete subject in the sentence is "grandfather," which is the noun performing the action of meeting many different people in his travels.
it is always better to have a relationship with your parents be4 someone else ypur parents are the people you can look up to when he/she breaks your heart :DDD

You call it a relationship
Two people who have the same great great grandfather are third cousins, second cousins, or first cousins, depending on how their descent runs for the great great grandfather. Since the two people have different surnames one or both of them are descended from a daughter, granddaughter or great granddaughter of the great great grandfather, and one or both of those women followed the custom of giving her children her husband's surname.
Yes
He got along well. Like normal people do
No one family, and no one answer to this question. As a grandfather (actually, a great grandfather) I would tend to back off, and let the parents meet fiancée on their own. Too many new people at one time can be stressful. I can met her later.
people can have different eye color because of the probalility that their parents have different eye color.
People mean a lot to different people based on their relationship and personality.
A competitive relationship?
a committed relationship of course
