It is quite possible that the Convict cichlid would kill a fish as small and slow as a Betta. I would not try to mix other peaceful species with large aggressive fish like Convicts.
It's quite possible that a convict cichlid would kill a betta fish, so they should not be in the same tank
you can put a betta in a 5 gallon tank
Do not put any sharp angular things in the tank and do not put another type of fish in your betta's tank.
No...betta fish are usually aggressive and might kill the angelfish.
fake plants my fish loves them
No. Bettas are freshwater fish. Seahorses are saltwater.

No
Yes.
yes of course! my betta is in a 2.5g and is perfectly fine
It depends on the type/brand of conditioner, and how much water is the Betta tank can hold.
No they cannot, also if you put two Betta fish together, they will fight.
yes yes
