@livid trout All of those can be prompted for, but it'll depend a bit on what genre you're after for how easy it is to influence. And you'll run into the typical headaches about prompting for duets and who actually does what.
A prompt I used for something along those lines (a fast rapped male voice, paired up with a female who sang the lines rhythmically rather than rapping) in the rapcore/nu metal genre was this:
Style: An upbeat, nu metal, alternative rock, rapcore track with fast-paced rapped lyrics over heavy synth, guitars and bass laying down a strong rhythm, The song features two nu metal singers, a male tenor with a smooth voice and a high energy female Alto
Lyric prompting:
[Verse 1 – Fast rapped, Male Tenor]
[Verse 2 - Melodic, Female Alto]
[Chorus - Duet, Melodic Hook]
[Haunting singing]
Lyric lines for the two singers
[Fast rapped, Male Tenor]
Single line for the male rapped voice
[Fast rapped, Female Alto]
Single line for the female singer
I remember it took a few attempts to get it sounding the way I had in mind, which was something loosely reminiscent of 90s/00s Linkin Park style tracks. The final version had lines that were 10-11 syllables long at 105bpm tempo for the rapped sections, and were notably shorter (c.8 syllables) when full singing in the chorus.
Style prompt was deliberately kept quite focused on a small-ish number of things that I wanted Suno to get right, with tweaks to that done in separate iterations using Cover once it had nailed the voices and general 'feel' of the song. Original began life in v4.5 before being remastered in v5.
Edit: If it helps, when it was re-uploaded to Suno after some tweaking in Audacity, Suno added this description which might also be useful to consider in the style prompt:
The song features a male vocalist with a raw, aggressive delivery, often employing a spoken-word style in the verses and a more melodic, female singer in the choruses
