Thank you in advance.

Added (1). The specs for my laptop to run world WorldEdit, i'm not going to run the server from my laptop i just need to know if WorldEdit consumes a lot of RAM when using it etc.

What kind of specs? If you mean for your server, it depends on how many players are on, and how many plugins you have. With no players beside you and no plugins, 1gb or ram should be plenty
