Name ideas for my 2 birbs?

So I got 2 "not hand-tamed" boys yesterday to mellow out my 3 crazy baby girlies! They're currently in quarantine together, and was just wondering what name ideas you can think of for them?

The green/blue boyyo is such a gentleman, he's very much unafraid and curious about his new birb parents! He is quite a bit older than the rest, does anyone have a possible age range of how old he might be? I know he's an adult based on his eyes and cere pigmentation, but he just looks like an older man because his cere looks a tad crusty. He is so chilled out, he doesn't fly away when I put my hand near him versus my other babies. I was thinking of maybe an old fashioned name for him since he's so sweet? Either that, or something that reminds you of him/looks like him?

My other blue/violet boy is a baby, he's definitely more nervous about perching on my fingers but since seeing his mate sitting on my finger, he too has done the same! I was thinking of maybe the name Storm for him, since I know some clouds get that violet sort of tinge during storms? And 2 of my girls are called Sunny and Sky?

I'm in love with these two, they are so adorable together! They love each other to bits and I'm excited yet a bit nervous to introduce them to my other babies. It's gonna be a rainbow in my cage!
