Hi And welcome to HC,
From what you have described it sounds all pretty normal, some Hamsters take many weeks to tame fully, some take a few days to a couple of weeks, the thing is to persevere and talk quietly to your Hammy he is coming to your hand and taking seeds and even putting his paws on you, sounds pretty good to me just keep at it ,try putting the seeds on one hand and letting him walk over the other hand to get to the seeds.
Bath tub bonding is supposed to be good too, but have never had to use it I have just worked at it as normal, if the hamster being tamed has shown interest then I work more at it, if not then I back off and always take it at their pace.
