Do these valves have a removable core?

No, they have the standard non removable core.

What's the weight on these tubes,1 reviewer says they are heavy, has any1 actually weighed them instead of assuming weight ?

I ordered the 700x18-25C tubes with 60mm presta valve. One weighs about 4.5oz / 128g.

Can I split the order into 2x 80mm and 2x 48mm valves?

I think I ordered 4 tubes , but I think you can order 2 of each
