Need help Identiflying these weeds

[Nicole edwards]

Can anyone tell me what these are and if they're safe for a sulcata.

Looks like a mixture of a few things
They're random little stalks of grass popping up everywhere and smell like onions when they're cut

The second picture has some edible stuff. I'm not 100%, but the one with purple flowers isn't edible. The one with little white flowers (what's primarily in there) is chickweed, edible.

The third is probably something from the onion (allium) family, definitely not grass. I wouldn't feed it.

Third looks like Chives to me, do they bloom with a purplish flower?
