As I have been learning about I2S there seems to be many designations for each line. Not sure why? by LR is the word clock. some times labeled WCLK, or LRCK never seen it labeled FS however. but the i2S wiki shows WS as a possible meaning WORD SELECT line...it is very confusing I agree

think of LRCK or FS, or WS as your samplerate, because they will always be the same speed as the samplerate; each left/right frame/sample/word.
it comes about because i2s was never developed as an interconnection standard between components for the consumer, but rather for chips on the same PCB, or at the very least part of the same design. there are many variants of i2s, PCM etc. so each manufacturer didnt really have other devices in mind when coming up with the naming.

no problem.
MCLK is your clock speed, not really officially part of the i2s 'standard'
FS/WS/LRCK are all the same thing. you will sometimes see clock speeds defined as 128/256/512 * FS and your dac max sample-rate will be defined by its MCLK and the max multiple
BCK, or SCK is bitclock/sampleclock
SDATA is the music data and you will see this multiplied out for multichannel SDATA1, SDATA2 etc
