2.Can I use 'meet with' or 'meet' to replace 'meet up' in the last sentence?

Answer

"Meet" and "meet up" can be used interchangeably, but "meet up" is informal.

Likewise, "meet with" and "meet up with" can be used interchangeably. "With" acts as a preposition so it needs an object.

Although "up" and "with" are both prepositions, "up" tends to cling to "meet" and cease to act as a preposition, as if "meet up" were just one word, a verb.

But not always!
When you use "up" as a preposition, the meaning changes:
"Santa Claus is the name of the gentleman I met up north."

Answer

‘Meet with’ requires an object.
I met with the professor.

Both ‘meet’ and ‘meet up’ can be used reflexively and are possible here. But ‘meet up’ is better as it conveys the reflexive meaning unambiguously.
