No, I don't believe you can. Those appear to be riveted construction, which means you'd have to drill the rivets out. Blocks with replaceable sheaves are bolted together. The blocks you've posted photos of are low-end models, which generally need to be replaced as a unit.
Unfortunately, your hand is in the way and I can't tell what the end on the second block looks like. It would help if you said what boat it was. It would also help if you said what kind of line it was used for. For Halyard and other relatively static lines, I'd recommend using Lewmar Synchro blocks. For more dynamically loaded lines, like sheets, I'd recommend using Harken Carbo Air Blocks.
Garhauer also makes some good blocks.
I'd also recommend you read the post in my signature.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
