Answer 1

I guess you can't change it. MonoSpace falls under Paragraph Style in Notes and it implies for whole sentence or paragraph.

Answer 2

You are changing paragraph style. If I understood correctly you probably look for ways to change font instead. After you have selected text hit ⌘ + T (will take to Fonts -> Show Fonts) select desired font and it will be applied to selected text only.
