I'd definitely advise against using the generic AG on him, and personally I'd hold out on r5. What does the rest of your 4/55 and 5/65 roster look like? What are your current goals and needs in-game?
If I were you, I'd wait for a Tech awakening gem before taking him to R5. The thing is, you'll have to keep hitting into the enemy's block to build up analysis charges, this a very slow and painful process.
You need his awakened ability to avoid this. It becomes SO easy to build up analysis charges when awakened. For now, keep him at R4, you can still do Variant 3 completion & exploration with an R4 unawakened Sentinel. Once you get a tech awakening gem. Take him straight to R5.
Yes Have r2 6* sentinel, his dupe only helps to ramp a little faster and more annoying on defance. Just learn how to safely hit 4 hit combo in block. Only red skull is a bad match for that so far. And some nodes like freezburn and countering robots
If variant 3 is your main goal he could easily do it, I 100% with a 4* he is insane in V3. See how you like him from there on a couple paths before awakening, R5ing etc.
Go for it. Not sure if many people know this but do a 5 hit combo into a sp1. The sp1 does enough hits to get you to somewhere around 45 charges. Its easy and i dont think he really needs the dupe to be very good. My 5* sentinel decimates mutants with full charges when you use an sp2 then a heavy since the shock does a lot of damage

I ranked my 6 star to r2 unduped... No regrets! Amazing champ to me
