Those first level spells seem fine to me.
Editing Working Spells.
Ahi - aid (on 2 domain lists), fog cloud, gust of wind, hideous laughter, invisibility perhaps.
Rahab - coming up shortly...
Hmm… I'm wondering whether hideous laughter wouldn't fit Rahab better considering he has the Madness domain.
He does have touch of madness from that Domain but that's significantly weaker than hideous laughter - the latter has range, requires no attack roll and forces its target prone.
How about swapping it for, say, glitterdust?
That'd make it aid, fog cloud, glitterdust, gust of wind, invisibility.
For Rahab, I'm thinking blindness, command undead, eagle's splendor, hideous laughter, whispering wind.
I'm thinking he might have a few undead thralls guarding his lair, and he seems the type to enjoy permanently blinding victims out of petty spite. The eagle's splendor is just to compensate a bit for his lower spell DCs.
