I think you should look at how you will be using your lights first, then find lights that fit the use rather than just buy the highest rated lights on CPF.
1) EDC.
1a) Keychain, always available as long as you have your keys.
1b) Goto light, pocketable or small holster. Don't really want to hold on keys every time a light is needed.
-
2) House light.
2a) General purpose, flooder preferred. Headlamp might be an option to have both hands free when fixing something.
2b) Long runtime for extended power outages. Lantern or tailstand flashlight with diffuser. Remember you cannot recharge batteries during a power outage!
2c) Low lumen bedside light for going to the bathroom without waking up the rest of the family.
2d) Blindingly bright bump in the night light. Wide hotspot so you can sweep large areas and/or easily blind an intruder.
-
3) Car light.
3a) General purpose, flooder preferred. Headlamp might be an option to have both hands free when fixing something. Must be able to buy replacement batteries on the road. Able to use primary lithiums (Energizer L91s or CR123As).
3b) Something other than 3a with a strobe so people don't drive into you. Can be your EDC.
-
4) Outdoor light. This will vary depending on the outdoors you wander around in.
4a) If you go down long unlit roads or cross fields you need a thrower.
4b) If there are lots of plants you need a warm white LED or an incan.
4c) A flooder works better than a thrower in a backyard.
-
5) Impress your friends.
5a) Throwers produce bright hotspots but beware friends with $5.99 6V lanterns that has upgraded the stock bulb with Xenon/Krypton/Halogen ones
5b) Small but bright - used to be an L0D-CE with 10440 but the 2AAA version of the Preon can do better with normal batteries.

Now let us look at the OP's list of lights:
1.Nitecore D10 - regular AA
Works For EDC-goto light.
2. Olight M20 R2 -- should i get these 18650 or 1232??
Works For going down long unlit roads or impress your friends.
Personally I think throwers are over-rated. Most of the time there is no need for maximum throw. When you really need maximum throw you better have your BIG HID ready. If I will be outdoors a lot I'd go for a warm white torch instead.
3. LumaPower D-Mini VX Ultra - 18650 or 1232??
Works For blindingly bright bump in the night light impress your friends.
4. TI Illuminati XP-g r5 -- includes battery
Works For EDC-keychain light.

Let us look at what the OP can look at next:
1) EDC is covered by the current list.
5) Impress yuor friends is covered by the current list.
2) House light.
2a) General purpose, The 2D $1 plastic incan. can do the job though a
Zebralight is better. Handheld or headlamp, even flood beam.
2b) Long runtime for extended power outages. Lantern or tailstand flashlight with diffuser. Remember you cannot recharge batteries during a power outage! I used to have a
4D AREALAMP with an LED bulb from a
Turtlelight. Nowadays you can just buy
this. Note the BIG D BATTERIES!
2c) Low lumen bedside light for going to the bathroom without waking up the rest of the family. 1AAA preon or Quark mini AA.
2d) Blindingly bright bump in the night light. Wide hotspot so you can sweep large areas and/or easily blind an intruder. OP's new #3 will do
3) Car light.
3a) General purpose, 2AA Fenix E20, LD20. The Zebralight work here too.
A gentleman bought one of Elektrolumens brighter lights. He reported in in ~3 weeks. His car had broken down at night. The reflections of his super duper light from the engine parts blinded him and he had a terrible time working on his car. Brighter is not always better!
4) Outdoor light.
4a) If you go down long unlit roads or cross fields you need a thrower. OP's #2 & #3 will do.
4b) If there are lots of plants you need a warm white LED or an incan. A Dereelight DBS or CL1H V3 with a Q4 5A/B will do. A Nitecore EZAAw is NOT bright enough.
4c) A flooder works better than a thrower in a backyard. Elektrolumens, Elektrolumens, Elektrolumens.
