[name]Oliver[/name]
[name]Levi[/name]
[name]Reilly[/name]
[name]Charly[/name]
Phinn
In no particular order.
[name]Oliver[/name]- I love this! I think its suits boys of all ages, and I love the nn [name]Ollie[/name].
[name]Levi[/name]- Not as keen on this, but its nice. Seems a bit too trendy for my liking.
[name]Reilly[/name]- Would this be pronounced as [name]Riley[/name]? [name]Even[/name] if its not, I think it seems really rather cute.
[name]Charly[/name]- Sorry, this seems a bit feminine to me, and more of a nn. You could go for [name]Charlie[/name], which I love, and it sounds a bit less nickname-y
Phinn- nn for [name]Phineas[/name] maybe? [name]Love[/name] it as a nickname!
[name]Oliver[/name] - I like it. I probably wouldn’t use it, but it’s handsome and charming and timeless. I always find it refreshing when I meet an [name]Oliver[/name]. Probably my favorite of your list.
[name]Levi[/name] - used to love it, but I’ve gotten over it, I guess. I like [name]Leo[/name] a lot more now.
[name]Reilly[/name] - love this for a boy! I prefer the [name]Riley[/name] spelling, though. It seems a bit more simple.
[name]Charly[/name] - I love [name]Charles[/name] nn [name]Charlie[/name] for a boy, but I’m not crazy about the [name]Charly[/name] spelling, or really using [name]Charlie[/name]/[name]Charly[/name] on its own without a full name.
Phinn - [name]LOVE[/name] [name]Finn[/name], but I’m not crazy about this spelling. Why not [name]Finn[/name]? Or what about [name]Phineas[/name], nn Phinn/[name]Finn[/name]/Phin?
If Phinn was [name]Phineas[/name] nn [name]Finn[/name], then that might get my vote. 
As they are, I like [name]Oliver[/name] the best.
Good luck!
[name]Oliver[/name] – I love this! It’s my favorite from your list. It’s classic and has a really cute nickname.
[name]Levi[/name] – I’ve never liked this as I have bad personal experiences with a guy by this name
[name]Reilly[/name] – [name]Love[/name] seeing this for a boy. It’s definitely my 2nd favorite on here.
[name]Charly[/name] – This just looks like a weird version of [name]Charlie[/name] to me
Phinn – I like it, but I think I like it better with the [name]Finn[/name] spelling…unless it’s a nickname of [name]Phineas[/name].
[name]Oliver[/name] - [name]Love[/name]
[name]Levi[/name] - Nice Biblical name, but somehow screams trendy to me.
[name]Reilly[/name] - I don’t really like it.
[name]Charly[/name] - Seems feminine. [name]How[/name] about [name]Charles[/name] nn [name]Charlie[/name]?
Phinn - I prefer [name]Finn[/name], [name]Flynn[/name], or [name]Phineas[/name].
