I am able to change font color, size etc when cell formatting. It is enough to fulfill users requirements for now.

Thank you for writing.
In RadMultiColumnComboBox you have direct access to popup grid by the EditorControl property. Thus, you can use the API that RadGridView offers for customizing the cells. You can either use the CellFormatting event or benefit from the conditional formatting. Feel free to use this approach which suits your requirement best.
I hope this information helps. Should you have further questions I would be glad to help.
