Can heat flow form an object with less internal energy to one with more internal energy?

Depends what you mean by "same internal energy". Heat flows from hotter temperatures to lower ones. A large cooler object may have the same internal energy as a smaller warmer one, but the heat will flow because of the difference in temperature.

For the first question, the answer is yes, quanta of energy will be exchanged, but there will be no NET flow of quanta. Both objects will retain the same temperature.
For the second, no, that won't happen. There can be no net flow of heat from a cooler object to a warmer one. That doesn't occur because the total entropy would decrease, which is not a spontaneous process.
