Please critique my baby name list

I like Anya and Lucas best.

Girls - Iris, Juno, Anya, Sabrina ok. Jolene conjures up that "Jolene, Jolene please don't steal my man" Dolly Parton song, Irene sounds a bit old womanish, June 1950s name a bit boring. Lauren nice but had it's day when my children were growing up now in their 30s.

Boys - Adam good solid, biblical, timeless. Leon - love it Rio no! Lukas okish, Fabian conjures up the Fabian Society a bit pretentious

Iris Jolene - Iris is fine name, popular right now though
Juno Irene - I like Juno, but it does feel very of the moment
Sabrina June - Sabrina is fine, not a name I'd choose but nothing wrong with it either. There's the teenage witch thing, but I don't think that's a dealbreaker. I've seen the name Sabrina come up on various name forums over the last couple of years a notable amount of times.
Anya Lauren - I love Anya.

Adam - very international and rather timeless and classless. Not an exciting name, but solid for sure.
Leon - I like Leon, but the massive popularity of Leo puts me off
Rio - not a huge fan of Rio. The two syllable name ending in O is a huge trend in boys names at the moment so all names of that style just kind of blend together somewhat.
Lukas - Lukas doesn't do anything for me, but it's popular and inoffensive. In the UK I'd default to the Lucas spelling as that's what most would assume, unless you have a reason to use the Lukas spelling. Obviously Lukas is the default spelling in man other countries though.
Fabian - really like Fabian, though not a fan of the long A sound that many in the UK use though.

I've not commented on middle names because they all sound kind of fine to me and middle names aren't really that important. In the absence of using a family name, I'd just choose another name I loved: Sabrina Juno sounds good. Generally with a two syllable surname I would avoid three consecutive two syllable names, as something like Adam Lukas Carter sounds clunky to me. Other names you might like Cecily, Clio, Gaia, Linnea, Marina; Felix, Lucien, Magnus, Robin, Stellan.

Iris and Adam

Adam, lukas and Leon are all OK.
For girls I like Iris, Juno and Lauren but none of the combinations. Of those I'd pick Iris Juno

I really like Adam and Leon. Lucas is OK, prefer that spelling.

From the girls I like Sabrina June a lot.

Your first names are nice but apart from June I'm not keen on the middle names. Going on the names you have I'd suggest:

Iris June
Iris Juno
Anya Iris
Juno Sabrina

Iris Jolene - love iris, not keen on jolene
Juno Irene - not really a fan of this one, but juno is cool
Sabrina June - again i like sabrina, not june
Anya Lauren - love this

Boys are even harder:
Adam - i like it
Leon - i like this too, it's different but still nice
Rio - this is cool
Lukas - prefer it with a c, but still a nice name
Fabian - not a fan

all in all i like most, but whatever you love is what you should go with!

I like Anya and Fabian

Iris Jolene - Iris is ok, not sure about Jolene. Iris Joely is better
Juno Irene - Irene (eye-reeny) is nice, not keen on Juno
Sabrina June - ok but Sabrina in quite a strong name
Anya Lauren - ok, not keen on Lauren

Boys are even harder:
Adam - ok
Leon - ok, prefer Leo
Rio - no
Lukas - ok
Fabian - not keen
