What do you mean by “only one link?”
You’ll need a different link for each block, as otherwise there’d be no way to tell each link which block it’s pointing to.
They’ll look like the following in edit mode:
[[note1#^someblockid]]
[[note1#^someotherblockid]]
[[note1#^anotherblockid]]
If you want to make each link only show the same visible text in preview, you can add an alias:
[[note1#^someblockid|Some text to show in preview mode]]
[[note1#^someotherblockid|Some text to show in preview mode]]
