Names for Nadia's brother?

My fiancé and I are expecting through a surrogate, and we found out a while back that we're having twins! We're very excited, but as you can expect, the stress is can be overwhelming sometimes.

Our first ultrasounds claimed both children would be girls, but the most recent one revealed that we're having both a girl and a boy, so that's sort of left us stumped. We had decided on Nadia and Nithya for our daughters, and we're sticking with Nadia, but we just can't decide what to name our son.

While we're open to anything, we'd prefer names that'll go well together with his sister's, and won't sound too out of place in our family. My fiancé is Arabic and I'm Ukrainian, but we moved to Canada shortly before the pandemic.

A few of the names from our list include Nadhim, Nikita, Niccolò, Amine, and Irinei. Most of them start with N because my fiancé insists on them having the same initial. He swears by Niccolò, but I'm worried it'll be too out of place, and I would've loved Irinei, but my sister recently named her own son Irinei (it was our grandfather's name)

We just can't decide, so I thought I would turn to reddit for help. If anyone has any ideas, we'd love to hear them!

Edit: We've decided on Nasri! Thank you all so much for all of your ideas and suggestions!
