Can I legally use the TM symbol before I apply for a trademark registration? Yes. But not the ® (circle r) symbol. Learn to use trademark symbols properly.

Select a font that allows the registered trademark symbol to be readable and legible. Most modern fonts include the registered trademark symbol, so you should not need to change fonts for the symbol.

Maybe and maybe not. This is an uncommon situation. A legal opinion will require additional facts and legal research.
