Conduction and convection require the presence of a medium (such as air or water) for the transfer of heat. In a vacuum, there is no medium to transfer heat, so conduction and convection cannot occur. Heat in a vacuum can only be transferred through radiation.

Convection is the primary mode of thermal energy transfer that occurs in fluids. In convection, heat is transferred through the movement of the fluid itself, either by natural (due to density differences) or forced (due to external energy input) convection.
Conduction, convection, and radiation are all processes of heat transfer, which involve the transfer of energy from a warmer object to a cooler object. The law of conservation of energy states that energy cannot be created or destroyed, only transferred or converted between different forms. In the case of heat transfer through conduction, convection, and radiation, the total amount of energy remains constant as it is transferred from one object to another.
The heated particles will move into the space were the bubbles are and stay there as they cannot escape for a bit. This will mean that the cup will stay warm as it will be sourrounded by captured heat energy.

Yes. Convection is a type of energy and a convection current is, well, the phrase for its currents. So yeah, convection and convection current are the same.

You don't transfer convection. Rather, convection is a process whereby heat energy is transferred.
Convection is the movement of particles due to a gradient of energy. Heat energy is thus transfered by the moving particles.
Mode of energy transfer in fluids is convection.
