This has probably been asked and answered in the past before, but is it possible to change the colors of the ihud keys? If so, how do i do that?

second question Can you also somehow move it from the up-right corner to bottom-right somehow?

To answer your first question, the command is "ihud_button_color <R> <G> <B> <OPACITY>" Don't include the brackets, just the numbers. I would keep the opacity at 255. To answer your second question, the command is "ihud_setpos bottom right". Also, please consider joining the Portal discord to ask any further questions, the src forums aren't really used.
