Help me identify plants ?

Hi there ! I am beginning to get my flowerbeds looking presentable The weeds are making for a lot of maintenance , but many of the plants my grandmother bought are re-emerging and many new wildflowers have invaded which make it more than rewarding enough.

I have discovered several plants that I havent seen before , and I hesitate to destroy them before identifying them first. There are tall ones with grayish green fluffy leaves , then quite a large plant with almost geranium like leaves , and then some small seedlings from a plant my mum claimed at first was tomato , but it doesn't look like the tomatoes I've seen :P . 

It is nothing vital , and I know that for the seedlings it may be a long shot, it is just curiosity getting the better of me , if anyone knows then I would be very grateful to you  

Thank you !
