Catch you later is casual, and it is almost the only example you have given where there are no errors :) .
“it was delighted talking with you as well.”
“it was delightful talking with you as well.” Very, very polite.
it was a pleasure to talking/talking with you”
it was a pleasure talking with you” Lose the "to" and it is fine. Also very polite. maybe you would use that on the telephone if you didn't know them.
Good/great meeting you ? Good, great, nice meeting you are all very close. All fine.
“delighted meeting you”
“delighted to meet you” You need the "to" with this one.
pleasure seems to be pretious and delighted seems inappropriate sometimes,is that right?
The word is pretentious, and not really, as long as the conversation requires a very polite reply. If it is a casual meeting, then yes, it would sound a bit odd.
You know, if you only used "Nice meeting you" all the time, you will be quite ok in almost every situation.
