Are any of these fish rare?

Hi,
I traded fish with someone, and they told me one of them was worth 300$. Looking at the pics can you tell?

I don't think they are that rare but they are nice first one looks like a electric blue ahli second is a jack Dempsey and the fourth looks like some kind of altolamprologus-compressiceps

Not that I can see but the fourth pic is a venustus

None of those fish are rare.

You have an electric blue hap,Jack Dempsey,Angel fish and what looks like a jaguar Cichlid to me.

If I were you I would rehome all these fish and start again.None of them are compatible with each other and if that is a Jaguar it will kill all the others as it grows.Your Angel fish will be the first to go.Their long fins will be too tempting a target.
Sorry to be the bearer of bad news but that's the way I see it.
You should do more research before you buy fish!!!

Or separate HUGE tanks for each!!!!! The last is for sure Jaguar and they get really really huge and are vicious but are wonderful in their own tank.... I had to rehome mine (two fry I was given) when they outgrew my largest tank!!! My floor wouldn't support anything more!!!
