The one at 09:36:20 is definitely lily of the valley. It looks pretty, smells lovely and will look after itself (and spread into the lawn if you let it, but you can keep it contained).
If it's your first year with the garden, wait and see what comes up. If you like it, keep it. If you like it but it spreads too much, grub lots of it up later in the year. If it spreads so easily that you go off it, get rid of it (this may take years...)
It looks to me as if you have some good stuff. Those interesting sprouts at 09:09:03 - no idea what they are, but they look hopeful and non-weedy.
