Can my wife use any contraceptive methods without she consents me even if I don’t want her to do?

The wife is not permitted to have contraception without the concept of her husband based on compulsory precaution. One should deal with each other to resolve any conflict regarding the issue of pregnancy or any other conflict in a good way as this is the best way for your marriage life.

If a Muslim leaves for work before dawn/before Morning Athan, can he offer his morning prayers before morning Athan as he doesn’t return home until late and on his way to work, he doesn’t have any other facility to offer it.

One can offer the prayer anywhere even not in a mosque after the time of the prayer’s Athan. The prayer before the time is not valid.

I live in a non-Muslim country and need to travel frequently. Due to the nature of travel and lack of facility of nearby mosque in the travelling city, I, often, end up missing my prayers and make it up at night. What compensation do I need to pay towards it?

It is not permissible to miss prayers. You can offer them even on the road and not in a mosque.
