I foster all the time and they are never puppies. I've had success training them all. The most important thing is to pick a style and stick with it. Everyone in the house has to be on board bc if they aren't they are basically sabotaging you and the training.

Potty training begins with feeding times. Feed at the same time each day and you can estimate what time they need to go out. Also take them out on a schedule so they can eventually come to expect a pattern. Dogs are creatures of habit.

For trick training, I would suggest to use feeding times for tricks. If you try to trick train when they aren't hungry, they won't be at their full attention. Conversely, don't feed all fatty "treats" for training and then they don't want to eat their regular food. Have a piece of food in your hand and lead the nose. The head will lead the body.

If you don't want to dogs on the furniture, when they jump up on it, say No or Uh uh and point off. When they jump off give them a treat. Or if you don't want them to jump off, pick them off and treat them, or say Good Boy. Sometimes simple petting is enough to let them know they did a behavior you like.

Make them wait at doors. You go thru doors first and they don't until you give them the ok. For this you need to teach "stay" or "wait". It's important to teach stay correctly. Do not have them stay for a bit them say "good" and then have them run to you. This just teaches them to stay for a bit then go running. Have them stay and you back away a few steps. Then you come back to them and treat. Lengthen the time and the distance each time until you can leave the room and they still stay.
