what kind of bonding is it?..

Does anybody have active working bonding?

sure

what kind? ospf, eoip(what mode of balancing balance-rr, xor..)? which is best for 2 wireless nv2 links

ethernet, balance-xor

-xor, I think. definitely not -rr

Ospf can double bandwidth?

You have already get an answer. If you don’t understand the way that ospf works, maybe you should learn.
