Plant/Tree Identification

Hello everyone. Apologies if I've put this in the wrong place but would anyone be able to help a complete novice (or whatever comes before a novice) in identifying these plants/trees (or indeed weeds)?

Thank you in advance.

 

5/ Bacopa, I think I can see cleavers(sticky willy)
6/ some sort of willow weed
7/ pansy, dandelion, bittercress
8/ cordyline red edge
9/ more willow weed and it looks like ribwort
That should give you something to look at in google!
I don't do trees so can't tell from the photos

 

Thank you @wiseowl for moving the thread and thank you @flounder, that's very helpful!

I've just bought a house and came across all these plants which I paid no attention to before buying! I'm hoping to look after them and plant others as I go on but I really am the definition of a novice.

Are there any amongst those which I should be looking to get rid of urgently?

Thanks again.

P.s. number 3 above has a very minty smell - is it too obvious to suggest it's a mint plant?

 

Ok, we'll go with mint for number 3!
With ID's, if you can get close ups of leaf, stem, any flowers it's a lot more helpful for a positive identification. I doubt I'm alone when I say I'm at an age where I squint at pictures

 

Haha thank you. I'll get some better images up next time I head over (my one daily exercise has been used up on getting those images I'm afraid ).
