Old light switch to wifi light switch

IF it is the supply.
If they go to two lights that you now want to switch separately
If they are loop in and loop out then no.
Yes.
I don't know what you mean.
All Neutrals - 2 or 3 - have to be connected together.

Ok, not using red but brown 
the guess work is two browns to com (L) and one brown to L1 or other way around, I would test as I have a tester to hand, permeant Line should go to L, but can't see a problem just trying to see which works.

Yes there are 3 neutrals over here. New wifi light switch requires one neutral. Says on a box etc. Should i use it? Or just connect L L1 and L2?
All Neutrals - 2, 3, 4 or more - must be connected together.
IMPORTANT:
Does the original switch control one or two lights?
Does this help you understand better?

Yes i think its more clear now. Since i have got only 1 light source - i guess i can take one neutral (out of 3) and connect it to a new light switch. Ive got only one L line and 2 are some kind of i loop i guess , but will try to put them in L1 and L2 first and see what happens
HMMT - All Neutrals must be connected together.
Then it might be like this:

Forgot to mention its a 3gang but will use 2 for wifi leds. There’ll be only 1 actual live ceiling light connected. I think im slowly getting there somehow. Wiring is not that easy i guess.
No, you said it was 3-gang. Ok - I think.
Just looks complicated. Do one bit at a time. Several parts all wired the same.

If i can have one last question.
I think this may be a loop wiring. Just seen youtube video with similar set up. Is this the final version of how it would look like with 1 light source? In the video guy connected 3x neutral to N. Then loop to L1 and live to N

Ok.
Typo?
Should be two loop lives to new switch L (the two wires from old switch L1) and one switched live to new switch L1 (the one wire from old switch COM).
