This is almost impossible to answer. It is too broad. Depending on whats wrong with the engine you might not need swapping. A rebuild is possible. But a 5S-FE engine for the 91 celica is fairly cheap for a low mile running engine. They came in a number of Toyota cars back in the 90's so there is no shortage of them. That's if you want the stock engine.. A more powerful turbo engine is available (from the celica alltrac, celica GT-4 and MR2 Turbo).. a bit more expensive with about the same amount of work..
If you need help or want further information, maybe just some questions answered i would suggest going to www.celicatech.com its a website dedicated to the Toyota celica.. And covers basically everything.
Yes, with some serious modifications
2jz swap, hands down the best choice.
a 3s-gte which is a 2.1 turbo is the easiest engine swap. this engine had 200 horsepower in the 5th generation. It was increased to 245 horsepower for the 6th generation celica. I have heard of a supra twin turbo being crammed under the hood a 5th generation celica, which can have upwards of 300 hp, but then you might as well just buy a supra as the cost of the swap would exceed the value of the car. edit: the 3sgte is a 2.0 turbo charged engine and it would be better to swap a 5sfe turbo

Yes. Check out www.celicatech.com for lots of swap information.
yep need a dif ecu though
Valves are not seating properly. Worn piston rings, cylinder sleaves and or blown Head gasket
It's possible to swap in a B20 series motor from a 3rd gen Prelude to a 5th gen Civic. However, it would be more practical (and easier to swap in) a D-series motor which there are multiple variants for the Civic between the late '80s into the '90s.
Yes, but you will need to swap over the lower mount bracket from your original engine onto the replacement engine. And you'll need to install a 1992-1998 timing chain cover onto the 1991 engine.
The engine swap could be possible, depending on the type of engines. Both the 1991 and 1994 engines will have to be the same size, or at least have the same mounting pattern.
It is not a direct swap. They are not the same engine. The Jeep is an old AMC engine, the other is Chrysler.
the 1991 Honda crx hf has the 1.5 liter motor unless a swap has been done
