I am adding a new tank to the house today, I have 2 back filtes on my other tank so I am going to put the used filter into the new tank today, and some gravel, can I add 3 fish from my other tank today or do I have to wait for a mini cycle?
setting up new tank with old filter from other tank, can I add fish right away?

you have to let the tank get stable in temperature first.
which usually takes more than 24 hours.
you should also dose the full volume of the tank with dechlorinator.
otherwise you should be fine.
unless you are adding 30 gallons worth of fish to a 10 gallon LOL
still go slow. the biologically active filter should be able to handle the load, and bacteria will begin to colonize your gravel bed over the next month.
that being said, don't add tons right now because if you overstress the filter without having the gravel bed established you could get a mini cycle.

I'd add them as soon as the filter is placed in the tank. You might want to keep an eye on your ammonia and nitrites for a week or so though.
I am adding the angel and the ram to this tank ( bolivian ram) there getting bullied by the other angel and the other ram. only 2 fish for this tank and a bristlenose if you think its ok. ( the tank is 20 gallons) I have added the filter, the water and the declor, and will head for the fish store for gravel I am also taking some of the gravel out of my other tank.
is this short term? 20 gal is a little small for a angel. should be ok for now just watch the water. do water change if you get any spikes.
yes, the angel is going into moms when i set it up in August. its a 55 so she will be fine short term. I always want whatts best for my babies, so I want her to have a wonderful home, I will be taking care of that tank to
Oh and mom is getting me a python so I am thrilled. bucketing these tanks is exausting when you have arthritis in hands and wrists and back 
Also when she has her tank established I am going to put the bolivian ram there to, then use my 20 for comunity tank, guppies, mollys and swords
and neons ( my kids want that kind of tank.
Also I do a water change on my tanks every 4 days, my tanks are clear and so pretty ( to me any ways thank you for your help and sugestions, this is one grateful lady
