I have been playing electric for about a year and a half and i was wondering if i should get a second guitar or should i upgrade my other guitar gears like pedals and maybe a new amp?

I also am not taking anything related to guitar at school, not in a band, but i do take lessons.

I have got to the stage where stuff like Remedy like seether is quite easy and i would like a suggestion on what guitar i should get if i do.

Depends if your happy with the guitar you have, the amp you have, and more or less what budget.
Gibson 58 RI VOS Custombuckers
Mesa Lonestar Special 2x12

If you're not happy with the guitar, get a new one. If you're happy with it, upgrade the amp and effects.
