In scale 1 to 10 how warm these gloves are?

I have long fingers, do these gloves have enough space? Also, I plan to use these gloves with computers (keyboard and mouse) so are these comfortable

Are the gloves warm enough?

Would these gloves work over a bodysuit that has gloves as well? I'm wondering if I could use these over a costume.
