Would this work for connecting a single footswitch output jack to separate reverb and gain jacks on the back of my amp?

Unless your footswitch output jack can pick up both sides of a stereo plug, you would be better off getting a Y cable that has mono plugs at all three ends.

with this I'm able to line out my guitar amp into 2 channels on my mixer? correct?

yes, usually the headphone output on whatever to individual inputs in a mixer, just be careful about the boost in signal

Would this connect the L/R outputs of a synth to a single input on an audio interface?

Yes, as long as the audio interface has a stereo input jack. You see that one end has 3 rings ... that means it's connecting a Left channel/Right channel/Ground connections all in one male 1/4" jack.

4x12 cabinet with 2-4ohm stereo inputs , amp has only 1-4ohm mono output, will this splitter work without damage to the amp ?

Don't do it. You need to use a speaker cable for a connection between a guitar amp and speaker cabinet, otherwise yes you can cause damage.
