We Spend Amazing Time Together and jack was so frankly,humble, and conservative.
If "frank" is applying to Jack, then it modifies a noun, (Jack), and therefore is an adjective, just like "humble" and "conservative" are adjectives. A comma should be put after it like "humble" has. The sentence should be written this way:
We spend amazing time together and Jack was so frank, humble, and conservative.
If you meant frank to apply to "humble", meaning that Jack acted truly humble, not just pretending to be humble, then "frank" modifies "humble". Since "humble" is an adjective modifying "Jack", you need the adverb form of "frank, which is "frankly". So the sentence should be written like this:
We spend amazing time together and Jack was so frankly humble and conservative.
There should be no comma between "frankly" and "humble", since "frankly" is modifying, (affecting), "humble", and you don't need a comma after humble either. First names and nicknames, (Jack is sometimes a nickname, sometimes a legitimate first name), should be capitalized unless the person has some kind of name they have adopted for show business, then it can be written without capitalization. For most normal applications, Jack should be capitalized.
"We" is correct, it is capitalized. "Spend Amazing Time Together" should NOT be capitalized UNLESS:
a. There is some specific company or place that calls itself "Spend Amazing Time Together", like a bar or hotel.
b. The writer wants to put special emphasis on that phrase, frequently in an ironic sense. To do so is pretty advanced writing, and I suggest you not do this until you are more familiar with written English. I only included this because you might come across an article or written piece on the internet where the writer does this, so I let you know that you can capitalize words that normally are not capitalized for a special advanced purpose.
That's the first sentence, I don't have time for the second at the moment. That sentence also has errors. I'm not criticizing you, but you asked. English is not easy to learn.
To save time, I will rewrite the second sentence one way it should be written, (there are other ways to write it correctly).
I hope he comes back here soon, in the next year, with his lovely wife and children. We wait for them.
