ID help — which of my garden visitors are actually my honeybees?

Bit of a soft question but I'm genuinely confused. Since getting my two hives this spring I keep 'recognising' my bees all over the garden, but my partner pointed out that half of them look nothing alike. There's a big round fuzzy one bumbling around the comfrey, a slim brownish one on the raspberries, and a small almost blue-black shiny one that's been going in and out of the holes in our fence posts. Are any of these actually mine? And is the shiny one something I should worry about near the hives? Feels silly to keep bees and not be able to tell what a honeybee looks like, but here we are.
