Should i change any of these options for FLAC?
Not if you want to keep the original number of audio channels.
i don't know what a audio channel is, will changing it affect the quality? the size of the audio source is 5 gb.

whether u want to keep the original or want them as .ac3 output. So if u decide for .ac3output select it and wait for it to output.
do i need to downmix?
if u like to downmix then choose it but if u want the channel to remain as it is choose keep original channel and sample rate.
Generally the audio will be either 5.1 channel surround sound (front left and right, centre, rear left and right and sub) or simply stereo, but there's a few other surround sound types. Whatever the format, selecting "keep original channels" will keep the audio channels as they are.
The other MeGUI option mainly used would be to downmix the surround sound audio to stereo (smaller file size) but there's a few other options to choose from.
The MP2 and MP3 encoder don't support multichannel audio, so if you choose one of them there's no "keep original channels" option as it must be mixed down to stereo.
