I’m making a game that can switch between First/Third person. I’m not sure how to go about making this with the character meshes though. I have arms and a character and what i was is, to have the first person mesh visible to only the player but the whole character visible to other players. And then when you switch to third have only the whole character visible to you and not the first person mesh. How would i be able to achieve this.? Also could it be done in blueprint or do i have to learn C++.
What you’re wanting to do is possible. You’ll want to take a look at the following video series on Networking along with our example Map for Networking in Content Examples from the Marketplace. This should be enough to get you started! 
The main area you’ll want to take note of for what the players see is called Replication.

Thanks Thats what i needed. But networking aside for right now. Lets say im in first person and i switch to third person. How would i make the fps arms not show up in the scene? Would i have to Toggle visiblity or something in a blueprint?
Yup!
You would set this up in the character blueprint. You would have the third person mesh and the first person mesh in your components area. You would need to uncheck the “visible” option. Then depending on which camera you are using and when you enable it to switch views you would simply enable/disable visibility for that particular mesh.
